Parameter Function
r2029[0...1] USS start not identified
Displays number of USS telegrams with unidentified start.
Index: See r2024
Note: Not used on MODBUS.
r2030[0...1] USS / MODBUS BCC /
CRC error
Displays number of USS / MODBUS telegrams with BCC / CRC error.
Index: See r2024
Note: See r2024
r2031[0...1] USS / MODBUS length
error
Displays number of USS / MODBUS telegrams with incorrect length.
Index: See r2024
Note: See r2024
P2034 MODBUS parity on
RS485
Parity of MODBUS telegrams on RS485.
0
1
2
Note: Also see P2010 for baudrate and P2035 for stop bit settings. You must set P2034 to 0 if P2035=2.
P2035 MODBUS stop bits on
RS485
Number of stop bits in MODBUS telegrams on RS485.
1
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
