B#16#02 Falling edgeA diagnostics alarm is generated and the ERROR LED flashes for each diagnostics event on
the module. The diagnostics alarms can be read out in the diagnostics buffer of the CPU, for
example. You can evaluate the error codes with the user program.
If the module is operated distributed with PROFIBUS DP in an ET 200MP system, you have
the option to read out diagnostics data with the instruction RDREC or RD_REC using data
record 0 and 1. The structure of the data records is available on the in the "Manual
for interface module IM 155-5 DP ST (6ES7155-5BA00-0AB0)".Impedance of encoder circuit too high Use a different encoder type or modify the wiring,
for example, using cables with larger cross-section
Wire break between the module and
sensor
Connect the cable
Channel not connected (open) • Disable diagnostics
• Connect encoder contacts with resistor:
– 16 kΩ ... 21 kΩ with 1.0 W at 24 VUC
– 37 kΩ ... 53 kΩ with 0.5 W at 48 VUC
– 101 kΩ ... 156 kΩ with 0.25 W at 125 VUC

relation to the mounting position of the /ET 200MP automation system and the
ambient temperature.The dimensional drawing of the module on the mounting rail, as well as a dimensional
drawing with open front cover, are provided in this appendix. Always observe the specified
dimensions for installations in cabinets, control rooms, etc.The data records of the module have an identical structure, regardless of whether you
configure the module with PROFIBUS DP or PROFINET IO.
Dependencies for configuration with GSD file
When a GSD file is used to configure a module, dependencies can arise when "assigning the
parameters".
There are no dependencies for this module. You can assign the individual parameters in any
combination.
Parameter assignment in the user program
You have the option to reconfigure the module in RUN (e.g. the input delay values of
selected channels can be edited without having an effect on the other channels).
Parameter assignment in RUN
The "WRREC" instruction is used to transfer the parameters to the module using data
records 0 to 15. The parameters set in STEP 7 do not change in the CPU, which means the
parameters set in STEP 7 are still valid after a restart.
The parameters are only checked for plausibility by the module after the transfer.
Output parameter STATUS
The module ignores errors that occurred during the transfer of parameters with the WRREC
instruction and continues operation with the previous parameter assignment. However, a
corresponding error code is written to the STATUS output parameter.
The description of the WRREC instruction and the error codes is available in the STEP 7
online help.
Operation of the module behind a PROFIBUS DP interface module
If the module is operated behind a PROFIBUS DP interface module, the parameter data
records 0 and 1 are not read back. You obtain the diagnostics data records 0 and 1 with the
read back parameter data records 0 and 1. You can find additional information in the
Interrupts section of the device manual for the PROFIBUS DP interface module in the For the configuration with 1 x 16-channel, the parameters are located in data records 0 to 15
and are assigned as follows:
● Data record 0 for channel 0
● Data record 1 for channel 1
● …
● Data record 14 for channel 14
● Data record 15 for channel 15
For the configuration as a 4 x 8-channel module, the module has 4 submodules with eight
channels each. The parameters for the channels are located in data records 0 to 7 and are
assigned as follows:
● Data records 0 to 7 for channels 0 to 7 (submodule 1)
● Data records 0 to 7 for channels 8 to 15 (submodule 2)
