Device Identification

Each FOUNDATION Fieldbus device has a unique device ID. The device ID is structured as
follows for the MIO device:
Manufacturer Idenification
502B46
= Pepperl+Fuchs
These 3 identification fields are identically structured for all FOUNDATION Fieldbus MIO
devices. If several MIO devices are connected to one FF-H1 segment, these devices are
differentiated via their individual 14-digit serial numbers. The serial number is also provided on
a label attached to the device.
4.4

Commissioning Procedure

The MIO device supports different modes of operation as described. For more information, see
chapter 4.1.
Depending on the mode of operation you selected, adhere to the commissioning procedure
that applies for this mode.
1. Read manual.
2. Start commissioning.
3. Set mode of operation MIO_MODE (resource block) to either one of the following modes:
1. Valve Coupler
2. Binary Input
3. Frequency Input
4. Counter Input
4. Complete commissioning.

Parameterization in Valve Coupler Mode

4.5.1

Interaction of Transducer Blocks and DO Function Blocks

In each of the DO function blocks, a reference value is calculated for the valve position in the
OUT_D parameter. This value is transferred to the transducer block that is connected with the
function block. A function block is connected to a transducer block through the Channel
function block parameter. This parameter contains the channel number 1 ... 4 of the transducer
block that the function block requires for interaction.
OUT_D of the function block can assume values from 0 ... 255. The value "0" means valve
"closed", values  0 mean valve "open".
Note!
Specifics of Reference Value
This specific reference value is contrary to many conventional devices where the value "0"
means "valve current OFF" and "1" means "valve current ON".
The transducer block accepts this reference value only if the status is GOOD (C) or
GOOD (NC). However, if the status is UNCERTAIN or BAD, the auxiliary valve is not controlled
electrically and the drive moves into the mechanical safety position.
If the current valve position is determined by 2 final position feedback sensors, the transducer
block transfers the current valve position back to the DO function block. The function block
represents the transferred value in the READBACK_D parameter. The numerical value
depends on the parameterization of the transducer block.
