l Set the device address for the module with the coding switch.
– Allowed device addresses are 1 ... 125.
– Every device address must only be assigned once on the bus.
– Changes to the device address are only adopted when the supply voltage
is switched on again.
LED Status Meaning
PW (green) on Module supply voltage on
ER (red) on
·
Incorrect data transmission on the backplane bus.
·
Internal fault
·
Lights up for approx. 1 second when the module is restarted
RD (green) See table below
DE (green) on Error−free communication with PROFIBUS−DP
PW (green) ER (red) RD (green) DE (green) Meaning
on on off off Self−test and initialisation in progress
on off blinking off Self−test and initialisation was successful
on blinking off off Initialisation error
on blinking blinking off
·
"ER" and "RD" blink asynchronously:
– Configuration faulty
·
"ER" and "RD" blink synchronously:
– Parameter settings faulty
on off on on
