Hi,

A project that I am working on now requires two SLC 5/04 talking to each other AND commmunicate with a SCADA individually.

I think the SLCs come with DH+ and RS-232 port. In this case, do i need to buy modbus modules or other commmunication modules in order to establish the communication between the SLC and the SCADA?

Thanks.

Hi

2 options:
A) DL3500-DH+/Modbus to go off the DH+ port that you have connected between the two SLC 5/04s.

B)DL4000-DMX to go off the RS232 CH0 of one of the SLC5/04s and then connect the two SLCs via DH+ for SLC to SLC communication.

The DL3500 DH+ solution will allow both SLCs to access the SCADA system if it is a MODBUS SLAVE or allow the SCADA system to access both SLCs if it is a MASTER.
