As shown in the following diagram, each function block of the E5AR/E5ER- DRT is electrically insulated. The following are functionally insulated from each other: 1) each of the inputs, 2) event inputs, voltage outputs, and current outputs, and 3) communications.
I/O Allocation The Configurator can be used to select any data from the list of allocation parameters for the Digital Controller and then allocate the data in a user-set destination. Data is selected by specifying the allocation number assigned to the desired parameter.
I/O Allocation Section 4-2 4-2-1 Allocation Area Size The size of allocated data in each of the IN and OUT Areas is shown in the following table. I/O memory Words Bytes Setting Allocated data Allocated data size: 2 bytes size: 4 bytes...
When Output Enable Bits are allocated in the IN Area, they are always set to 0 (OFF). Note If data allocated to the IN or OUT Area is changed, use a software reset or cycle the power to enable the new settings. 4-2-3 Allocation Default Values The default values for I/O allocations are listed in the following table.

(b) Control output (both heating and cooling sides) is always OFF for linear outputs.

SP has already been set. If the Output Enable Bits are set to 1 and then set to 0, no SP will be writ- ten even if one is accidentally allocated. (However, care must be taken because writing is enabled if Output Enable Bits are set to 1.)
Lower byte Related information Bit 15 is strobe 2 and bit 14 is strobe 1. A logical OR is taken between the two leftmost bits of the command code and bits 15 and 14, and the result is attached as the strobe to the operation command. The command code for E5AR/ER operation commands is 0@ hex, so when the logical OR is 8@ hex, the strobe is ON.
(CIO 3209 when the default I/O allocation (fixed allocation area 1) is set.) Operation commands are executed only when the Output Enable Bit is set to 1 (ON) and the strobe is ON. The strobe is ON when the following two condi- tions are met: 1.
Page 61
• The contents of D1000 (= 0100 hex) is copied to CIO 3209, where the operation command is allocated. • The strobe is turned ON (strobe 1 = 0 and strobe 2 = 1) and the operation command is executed. The RUN/STOP status is checked and the strobe is disabled for RUN (to prevent unintentional setting changes.)
Page 62
MOV (021) 000001 Copies the contents of D1000 (000004) to CIO 3209. D1000 Execution condition 3209 ASL (025) Shifts the contents of CIO 0000 one bit to the left. 0.01 RESET 000002 Sets strobe 1 = 0. (000007) 3209.14 ASL (025) Shifts the contents of CIO 0000 one bit to the left.
Output Enable Bit (CIO 320100) is used to write SP. Operation • The value used as SP is set in D1000 and D1001 at the start of the ladder program. In this example, the SP is set to 100.0, so the hexadecimal number 03E8 is written to D1000.
Explicit message communications can be used to send and receive data that is not allocated in the IN and OUT Areas due to word size restrictions, and data that does not require the frequent refreshing used by the IN Area and OUT Area.
The Attribute ID does not need to be specified for some commands. Data Specifies the details of the commands, set values, etc. The data section is not required for read commands. Response Block The following format is used when a normal response is returned for the sent explicit message.
(bit 07) turned ON is returned. (For example, when the service code of the command is 0E hex, the service code of the response will be 8E hex.) When an error response is returned for the explicit message, the service code is always 94 hex.
CompoWay/F Binary Commands CompoWay/F binary commands use hexadecimal values for the CompoWay/ F frames, and not ASCII. Therefore, the data volume is about half of Compo- Way/F ASCII commands. The following restrictions apply. • Read Controller Attribute (05 03), which includes ASCII in the Compo- Way/F frame, cannot be used.
For details on sending explicit messages from an OMRON Master PLC, refer to the DeviceNet Master Unit operation manual. Note The number of digits used for the Class ID, Instance ID, and Attribute ID depends on the master used. When sending parameters from an OMRON...

I/O Response Time The I/O response time is the time required from when the master is notified of an input on an input slave until an output is made on an output slave (includ- ing ladder diagram processing in the PLC).
Total communications cycle time = IN communications cycle time + OUT com- munications cycle time. ■ IN Communications Cycle Time IN communications cycle time = (39 ms + 8 ms x number of allocated data) + (6 ms × total allocated words in IN Areas 1 and 2)
+ (7 ms × total allocated words in OUT Areas 1 and 2) Refresh Processing The refresh processing time is the time required for the CPU Unit of the PLC Time and the DeviceNet Master Unit to pass I/O information back and forth. The cycle time of the PLC is affected as described below when a DeviceNet Unit is mounted.
Page 76
I/O communications are set to start automatically at startup. The system startup time is the delay from the time that the Master Unit is turned ON or restarted until the time remote I/O com- munications begin.
If a send or receive message is corrupted, a record will be stored in the error log in the Master Unit. Use a FINS command to read the error record or use the Configurator to monitor the error log.
Page 78
If network traffic is concen- trated on one Master Unit, long times will be required that those produced by the above calculations. Be sure to consider this when designing the system.
Indicators and Error Processing Section 7-1 Indicators and Error Processing The following table lists the indicator status when errors occur, the probable causes and processing. Indicator status Probable cause Remedy MS: OFF The power is not being Supply communications power from supplied to the Control- the DeviceNet connector.
• Wipe the Controller with a dry, soft cloth for regular cleaning. • When dust or dirt cannot be removed with a dry cloth, dampen the cloth with a neutral cleanser (2%), wring out the cloth, and wipe the Controller.

Replacing Controllers The Network consists of the DeviceNet Master Unit and Slave Units. The entire network is affected when a Unit is faulty, so a faulty Unit must be repaired or replaced quickly. We recommend having spare Units available to restore Network operation as quickly as possible.
