Communicating with the PLC
7.1 USS communication
No. Description
101 Parameter is currently deactivated; parameter has no function in the present converter status
102 Communication channel width is insufficient for response; dependent on the number of PKW and the maximum
net data length of the converter
104 Illegal parameter value
105 Parameter is indexed
106 Request is not included/task is not supported
109 PKW request access timeout/number of retries is exceeded/wait for response from CPU side
110 Parameter value cannot be changed (parameter is locked)
200/201 Changed lower/upper limits exceeded
202/203 No display on the BOP
204 The available access authorization does not cover parameter changes
300 Array elements differ

Setting
= 30: restores to factory settings
Possible settings:
= 1: resets all parameters (not user defaults) to their default
values
= 21: resets all parameters and all user defaults to factory
reset state
Note: Parameters P2010, P2011, P2023 retain their values after
a factory reset.
= 3
= 5: USS/MODBUS on RS485
Factory default: 1 (operator panel)
= 5: USS/MODBUS on RS485
Factory default: 1 (MOP setpoint)
= 1: USS (factory default)
Note: After changing P2023, powercycle the converter. During the
powercycle, wait until LED has gone off or the display has gone
blank (may take a few seconds) before re-applying power. If
P2023 has been changed via a PLC, make sure the change has
been saved to EEPROM via P0971.
Possible settings:
= 6: 9600 bps (factory default)
= 7: 19200 bps
= 8: 38400 bps
...
= 12: 115200 bps
Sets the unique address for the converter.
Range: 0 to 31 (factory default: 0)
Defines the number of 16-bit words in PZD part of USS telegram.
Range: 0 to 8 (factory default: 2)
