2
Note: Also see P2010 for baudrate and P2034 for parity settings. You must set P2035 to 2 if P2034=0.
r2036.0...15 BO: CtrlWrd1 from
USS/MODBUS on RS485
Displays control word 1 from USS/MODBUS on RS485 (i.e. word 1 within USS/MODBUS = PZD1). See
r0054 for the bit field description.
Dependency: See P2012
r2037.0...15 BO: CtrlWrd2 from USS
on RS485 (USS)
Displays control word 2 from USS on RS485 (i.e. word 4 within USS = PZD4). See r0055 for the bit field
description.
Dependency: See P2012
Note: To enable the external fault (r2037 bit 13) facility via USS, the following parameters must be set:
P2012 = 4
•
P2106 = 1
