Parameters

Module/channel parameters

Definition
Module/channel parameters are specific parameters whose configuration can affect the entire module or the channels.

Description
The following module/channel parameters are available:

Table 6-1 Parameters and their defaults

Parameter	Value range	Default	Parameter reassignment in RUN	Efficiency range
Diagnostics for Missing supply voltage L+ (see "Diagnostics for Missing supply voltage L+")	Enabled Disabled	Enabled	Yes	Module
Diagnostics for Wire break (see "Diagnostics for Wire break")¹	Enabled Disabled	Enabled	Yes	Channel
Wire break check (see "Wire break check")	Enabled Disabled	Enabled	Yes	Channel
Channel activated (see "Channel activated")	Enabled Disabled	Enabled	Yes	Channel
Input delay (see "Input delay")¹ for channels 0...7	None 0.05 ms 0.1 ms 0.4 ms 0.8 ms • 1.6 ms • 3.2 ms • 12.8 ms • 20 ms	3.2 ms	Yes	Channel
Input delay (see "Input delay") for channels 8...15	3.2 ms	3.2 ms	No	Channel
Hardware interrupts positive edge (see "Hardware interrupts positive edge")²	Enabled Disabled	Disabled	Yes	Channel
Hardware interrupts negative edge (see "Hardware interrupts negative edge")²	Enabled Disabled	Disabled	Yes	Channel
Potential group (see "Potential group")	Potential group of the left module (dark gray terminal block) New potential group (light gray terminal block) No potential group (black terminal block)	Use potential group of the left module	No	Module

¹ The input delay is switched off on all channels when high precision time stamping is activated. When high precision time stamping is activated, pulse stretching and the rising/falling edge hardware interrupt are deactivated on all channels (not adjustable).

Parameter reassignment

Definition
Each configuration change resets the corresponding reaction. Changing the configuration of a function does not affect other functions.

Explanation of the module/channel parameters

Diagnostics for Missing supply voltage L+

Definition
Enabling of the diagnostics for detecting missing or insufficient supply voltage L+.

Diagnostics for Wire break

Definition
When wire-break diagnostics is activated, you can enable wire-break diagnostics for insufficient current flow on the input.

Note
The wire break diagnostics can only be enabled when the "Check for wire break" parameter is enabled. If you use a simple encoder contact, you need to connect a parallel resistor to enable wire break diagnostics in the open state (sensor resistance for wire break diagnostics: 15 kΩ to 47 kΩ).

Example

Wire break check

Definition
Enables the wire break check. The wire break check must be enabled in order for the I/O module to detect a wire break.

Channel activated

Definition
Specifies whether a channel is activated or deactivated.

Input delay

Definition
This parameter can be used to avoid signal faults. Changes to the signal are only detected if they are constantly pending longer than the set input delay time.
For input channels with longer input delays, the read-in time is moved accordingly. This means individual channels can be assigned input delays, if necessary, without having a negative impact on the possible cycle time.

Hardware interrupts positive edge

Definition
Specifies if a hardware interrupt should be generated for a rising edge.

Hardware interrupts negative edge

Definition
Specifies if a hardware interrupt should be generated for a negative edge.

Potential group

Definition
A potential group consists of a group of directly adjacent I/O modules within an ET 200SP HA station that are supplied via a common supply voltage.

Description
A potential group is built up from left to right by using terminal blocks.
A new potential group starts on the left side with a light gray terminal block, via which the supply voltage for the potential group is fed in.
The potential group is continued to the right with dark gray terminal blocks and ends when a new potential group is built up next to it.
The potential group also ends if there is a black terminal block next to it. Black terminal blocks are fed individually and cannot be included in potential groups.
You can find additional information on the configuration of the potential group in the system manual SIMATIC; Distributed I/O System; ET 200SP HA.

Displays and interrupts

Status and error displays

Definition
The LED displays are status and error indicators.
Diagnostics messages and maintenance events, as well as their possible causes or solutions, are described in the diagnostics messages and maintenance events.

Cycle time
The cycle time describes the time slice in which signals from the inputs are acquired and processed. The cycle time of the I/O module is 1 ms (250 μs for time stamping).

Minimum pulse length
In order for a pulse or an edge transition to be reliably detected by the I/O module, the signal status must be active for at least the duration of the minimum pulse length.
In non-redundant mode, the minimum pulse length is greater than the input delay and greater than the cycle time.

Drivers/parameters/diagnostics messages and address space

Parameter assignment

Parameter assignment in the user program
You can reconfigure individual channels of the module in RUN without this having an effect on the other channels.

Changing parameters in RUN
The parameters are transferred to the module with the "WRREC" instruction via data record 128.

Output parameter STATUS
If errors occur when transferring parameters with the "WRREC" instruction, the module continues operation with the previous parameter assignment. The STATUS output parameter contains the corresponding error code.
The STATUS output parameter is 4 bytes long and is configured as followed:

Byte1: Function_Num, general error code
Byte2: Error_Decode, location of the error code
Byte3: Error_Code_1, error code
Byte4: Error_Code_2, manufacturer-specific extension of the error code

Module-specific errors are displayed via Error_Decode = 0x80 and Error_Code_1 / Error_Code_2.

Error_ Code_1	Error_Code_2	Cause	Remedy
0xB0	0x00	Number of the data record unknown	Enter valid number for data record.
0xB1	0x01	Length of the data record is incorrect	Enter valid value for data record length.
0xB2	variable	Module cannot be reached	Check station - is the module plugged in correctly? Check the parameters of the WRREC instruction.
0xE0	0x01	Wrong version in the header	Correct the version number of the parameter block.
0xE0	0x02	Header error (number or length of parameter block)	Correct the length and number of the parameter blocks.
0xE1	0x01	Reserved bit set	Check and correct the parameters
0xE1	0x02	Invalid diagnostics enable bit set for operating mode
0xE1	0x03	Invalid hardware interrupt enable bit set for operating mode
0xE1	0x07	Invalid coding for input delay

Parameter assignment and structure of the module/channel parameters

Structure of data record 128 (Fig. A-1)
Data record 128 has a length of 44 bytes.
It contains module parameters as well as channel or technology parameters of the 16 channels; 2 bytes each.

Header information and module parameters (Fig. A-2)
The following figure shows the configuration of the header information and module parameters.

Channel parameters (Fig. A-3)
Every channel parameter block contains the channel parameters for the digital input (2 bytes).
The following figure shows the configuration of the channel parameters for channels 0 to 15.
x = 12 + (channel number * 2); with channel number 0...15
All unused bits and the bits or bytes marked as "reserved" must be set to zero.
You activate a channel parameter by setting the corresponding bit to "1" or the corresponding value.
Structure of Channel parameters

Diagnostics messages

Diagnostics alarms
A diagnostics message is generated for each diagnostics event and the DIAG LED on the DI 16×24VDC NPN flashes red or the MT LED lights up yellow.
In addition, channel-specific channel diagnostics are displayed through the corresponding channel error/status LEDs.
The diagnostics messages can be read in the diagnostics buffer of the CPU, for example.
Diagnostic messages are assigned either channel-specific to an input or assigned as module messages to all inputs. All channels are switched off for diagnostics messages that affect the entire module. Only the corresponding digital input is affected by diagnostics messages, which refer to individual channels.

Table A-1 Diagnostic messages, their meanings and remedy options

Diagnostics message	Error code	Assignment	Meaning	Remedy
Wire break	6_H	Channel	Impedance of encoder circuitry is too high	Use another type of encoder or wiring, for example, use conductors with a larger cross-section
			Wire break between the module and sensor	Connect the cable
			Channel not connected (open)	Disable diagnostics Connect encoder contacts with a 15 kΩ to 47 kΩ resistor¹) Switch off wire break check
Parameter assignment error	10_H	Module	Parameter assignment does not match the terminal block used Incorrect parameter assignment	Correct the parameter assignment Check terminal block²)
Supply voltage missing	11_H	Module	Missing or insufficient supply voltage L+	Check the supply voltage L+ on the terminal block Check terminal block
Hardware interrupt lost	16_H	Module	Error is reported because the events occur faster than they can be processed in the system.
Channel/component temporarily unavailable	1F_H	Module	Firmware update is in progress or has been canceled during the update. The module does not read any process values in this state.	Restart the firmware update Wait for firmware update
Inconsistent parameter assignment	123_H	Module	Errors in the redundancy parameters sent to the module	Check the parameter assignment
Retentive memory in carrier module defective	154_H	Module	Fault detected in the memory block on the carrier module during startup.	Replace carrier module
Retentive memory in the terminal block defective	155_H	Module	Fault detected in the memory block on the terminal block during startup.	Replace terminal block

¹⁾ 47 kΩ resistors can be used provided that the following supplementary conditions are complied with: Only singular structure of the I/O modules (no IO redundancy); the process cables are shielded; no certification required according to the following standards: NE21 or Power Station 6100-6-5
²⁾Only the terminal blocks (TB 45R...) are suitable for use with I/O modules in IO redundancy.

Maintenance events

Maintenance events
A maintenance event is generated for each maintenance required identified. The MT LED lights up on the module.
Maintenance messages do not have a direct influence on the functions of the module or digital inputs.

Maintenance message	Error code	Assignment	Meaning / Cause	Remedy
Retentive memory in carrier module defective	154_H	Module	Fault detected in the memory block on the carrier module during operation.	Replace carrier module
Retentive memory in the terminal block defective	155_H	Module	Fault detected in the memory block on the terminal block during operation.	Replace terminal block

Hardware interrupts

Hardware interrupts
The DI 16×24VDC NPN generates a hardware interrupt for the following events:

At a rising edge (signal change from 0 to 1)
At a falling edge (signal change from 1 to 0)

Interrupt OBs are called automatically if an interrupt occurs.
You can find detailed information on the event in the hardware interrupt organization block with the "RALRM" instruction (read additional interrupt information).
The module channel that triggered the hardware interrupt is recorded in the start information of the OB40 in the OB40_POINT_ADDR tag. The figure A-4 below shows the assignment to the bits of local data double word 8.
Start information of the organization block

Address space

Abbreviations

"IB" stands for input byte, that is, the module start address in the input area
"DI" stands for digital input
"QDIn" stands for the value status (QI) of digital input n

Address space
The following table shows the mapping of the address space of the DI 16x24VDC NPN.

Table A-2 Address space of the DI 16x24VDC NPN

IB x +	7	6	5	4	3	2	1	0
0	DI7	DI6	DI5	DI4	DI3	DI2	DI1	DI0

3	QDI15	QDI14	QDI13	QDI12	QDI11	QDI10	QDI9	QDI8

Evaluate value status
There is a bit value status for each digital input in the input address space.
Irrespective of the diagnostics enables, each value status (each QI bit) provides information on the validity of the corresponding process value.

Value status = 1: Process value okay, "good"
Value status = 0: Process value not okay, "bad"

Basically, the value status is set to "good" if the digital value can be detected without error. The value status is set to "bad" in the following cases:
