Hi all,
I am doing communication between Micrologix 1400 and ABB softstarter through modbus ,below I have mentioned details.
System:-
We have Micrologix 1400 with 1763-NC01 (Connected to channel0)to communicate with ABB softstarter
Protocol to be used :-ModbusRTU
Media :- RS-485
Following are the Settings done in SoftStarter
F055- Enable Communication
F056-19.2, Baud Rate
F057-01 ,Slave Address
Following are the settings made in Modscan (pc) to communicate with soft starter through the help of RS232-485 converter and it is communicating.
Baudrate:- 19200
Wordlength:-8
Parity-Even/Odd- It is working with both Parities and not working with Parity “NONE”
Stopbits-1
Cable connection used is straight ie:- D+ to D+,D- to D-,Sheild to shield
Also I have succeeded to make communication between PLC and PC with Modsim.So it is confirmed that both softstarter and PLC is working with pc
Problem:- PLC is not communicating with Soft starter,
cable connection details as BELOW:-
d+ connected to B in 176-nc01
d- connected A in 176-nc01
Sheild connected to COM in 176-nc01
Please find the Enclosed Rslogix500 file to see the configuration for channel0
