of the IO modules (no IO redundancy); the process cables are shielded; no certification required according to the following
standards: NE21 or Power Station 6100-6-5.
Only the terminal blocks (TB 45 ...) are suitable for use of IO modules in IO redundancy.

Maintenance events

Maintenance events
A maintenance event is generated whenever maintenance is required. The MT LED lights up on
the module.

Assignment Meaning
Digital input Impedance of encoder circuitry is too
high
Wire break between the module and
sensor
Channel not connected (open)
Module
• Parameter assignment does not
match the terminal block used
• Incorrect parameter assignment
Module Missing or insufficient supply voltage
L+
Module Update of the firmware is being per‐
formed or has been canceled.
The module does not import any
process values during this time.
Module Error is reported because the events
occur faster than they can be pro‐
cessed in the system
Module Internal module error has occurred
Module A memory block fault on the support
module was detected during start-up
Module A memory block fault on the terminal
block was detected during start-up
Solution
Use a different encoder type or
modify the wiring, for example,
using cables with a larger cross-
section
Connect the cable
• Disable diagnostics
• Connect encoder contacts
with a 15 kΩ to 18 kΩ resistor
• Correct the parameter assign‐
ment
• Check terminal block
• Check wiring of the supply
voltage L+ on the terminal
block
• Check the terminal block type
• Restart firmware update
• Wait for firmware update
Replace I/O module
Replace carrier module
Replace terminal block
