3 Software Configuration
This chapter describes how to configure the MTQ22-FBP and the PSE to enable Modbus communication.
3.1 PSE Softstarter
The following list of instructions explains how to configure the fieldbus parameters on the PSE softstarter.
1. Fieldbus Control
This parameter is used for configuration of the fieldbus communication. Connecting the PSE Softstarter to the
Fieldbus plug automatically enables fieldbus communication. To enable control of the softstarter using fieldbus,
this parameter must be set to On. If Fieldbus Control is set to OFF, fieldbus can only be used for monitoring
softstarter data.
If this parameter is set to On, the softstarter might trip on fieldbus
fault if no fieldbus communication is available. If the intention is
to run without fieldbus control, this parameter should be set to
OFF.
2. Fieldbus Address
The parameter Fieldbus Address allows setting of address for the fieldbus communication. The setting range for
the fieldbus address is 0...255. If the address is set to 255, the address stored in internal memory of the fieldbus
plug will be used.
It is possible to read and set this parameter via the keypad when Fieldbus Control is set to On or OFF.
Changing this parameter will automatically reset the fieldbus
interface and the new address will be active. If MTQ22-FBP was
communicating with the old address, the MTQ22-FBP needs to be
re-configured and the PSE restarted.
