Good morning all,
I'm having issues with one of our DH+ networks. When ever I connect to the DH+ network for our boiler and evaps PLC Processors shortly after I get booted off. The message displayed is "loss of communications to processor". There are 3 PLC 5 processors and a HMI computer on this network as well as a delta v system that communicates to the PLC via DH+. The processors used are a PLC 5/40. 2 out of the 3 processors boot me off the DH+ intermittently with the comms loss message (Evaps and 16Burn PLC). The operators of the boiler use the Delta V HMI to communicate to the PLC. They are trying to light the Boiler but having issues as the comms loss to the Delta V is preventing them to do so. Any tips on trouble shooting a DH+ network or someone with past experiences on this issue would be welcomed.
Thanks, Tex
