Counter Input Variables
The OUT_C variable consists of 5 bytes. The first 4 bytes contain the process value of the
frequency or counter. The 5th byte contains the status of the process value.
For the counter input the sensor value is formatted in unsigned 32.
The structure of the 5th byte, containing the input status, is as follows:
Counter Output Variable OUT_C_RESET
The variable OUT_C_RESET contains the reset value in counter mode.
■
= 0: Counter is in normal operation.
■
> 0: Counter is in reset mode. As long as the counter is in reset mode, the following
applies:
•
OUT_C variable = 0
•
OUT_C.status = 0x4F (uncertain-initial value-const.)

Cyclic Communication Data Structure
In the following section explains the order of the module data transmitted in the cyclic data
exchange.
4.4.1
Valve Coupler Mode and FD0-VC-Ex4.PA Compatibility Mode
The length of the module data depends on the module type. For more information, see chapter
4.2.
If an
“
empty
”
module is used instead of a module containing data, no data is transferred during
the data exchange for the corresponding channel.
Classic Status Value Mnemonic
Description
0x80
GOOD-OK
No error, the input value is valid.
0x12
BAD-SF
(Sensor failure.)
Lead breakage.
0x0C
BAD-DF
(Device failure.)
Hardware fault.
0x1C
BAD-OS
(Out of specification.)
No valid value of the sensor has been read
(after power-up of the device).

Note!
Discrete Input Modules
Discrete input (DI) modules are supported in the
MIO mode
for valve couplers only. These are
the OUT_D variables of the position feedback sensors. These variables work as described in
the section "Discrete Input Variables", see chapter 4.3.2.
