The communications parameters are defined in accordance with the operating mode:
Operating mode Default parameters Modification of parameters
Active 9,600 baud
No parity
8 data bits
1 stop bit
Parameters cannot be modified
Passive No default parameters defined Parameters are defined in the user
program by using the SINIT
function
MODBUS

9,600 baud
No parity
8 data bits
1 stop bit
Parameters are modified in the user
program using the SINIT function
Õ Absolute identifier: KW 00,06
Õ Symbolic identifier: MODE_SST
Õ Meaning of the value of the constants:
The constant is a 5-digit decimal number
KW 00.06 =
Example:
MODBUS master Mode = 100
Slave no. = 217
Time delay = 1000
RTS signal inverted: 10000
Calculate entry in KW 00,06
KW 00,06 = 100 + 217 + 1000 + 10000 = 11317
KW 00,06 = 0 (Default) + cable 07SK50/52 Active mode
KW 00,06 = 0 + cable 07SK51/53 Passive mode (ASCII
mode)
KW 00,06 = 1 + cable 07SK50/52 Active mode
KW 00,06 = 2 + cable 07SK50/52 Passive mode (ASCII
mode)
Modbus operation only with cable 07SK51/53
KW 00,06 = 100 Modbus master
KW 00,06 = 100 + slave no.
