4.26.8.7 Register description
4.26.8.7.1 Function model 1 - Standard
Read Write Register Fixed offset Name Data type
Cyclic Non-cyclic Cyclic Non-cyclic
Module status USINT
StatusFuse Bit 0
0 1
StatusPowerSupply Bit 1

2 2 Counter01 USINT ●
Fixed modules require their data points to be in a specific order in the X2X frame. Cyclic access occurs according
to a predefined offset, not based on the register address.
Non-cyclic access continues to be based on the register numbers.
4.26.8.7.2 Function model 254 - Bus controller

4.26.8.7.4 Counter for the voltage dips
Name:
Counter01
This register is used to count how often the voltage dips on the PD module.
Data type Value
USINT 0 to 255
4.26.8.7.5 Minimum cycle time
The minimum cycle time defines how far the bus cycle can be reduced without communication errors occurring.
It should be noted that very fast cycles decrease the idle time available for handling monitoring, diagnostics and
acyclic commands.
Minimum cycle time
100 μs
4.26.8.7.6 Minimum I/O update time
The minimum I/O update time defines how far the bus cycle can be reduced while still allowing an I/O update to
take place in each cycle.
Minimum I/O update time
100 µs
