Regarding Honeywell TPS system communication DP communication
Thread Content
It seems there are quite a few people here who are familiar with Honey’s system. Everyone, please help take a look. Recently, I encountered the need to communicate with the DP of the TPS system, and after looking up some information from Honeywell, it seems that only the current PKS version supports DP, while TPS does not appear to support it. If it’s not possible to use DP communication, MODBUS is extremely slow, which is frustrating.
Can it be converted in the middle? Use the APP to convert to OPC and then to DP
I don’t know much about HONEYWELL, but I believe PROFIBUS is a widely used bus, so HONEYWELL must have modules that support the DP interface. If you’re not sure, you can contact the distributor.
I think TPS isn’t supported; the issue is that it’s still too early. At that time, DP hadn’t yet been officially established as an international standard. I don’t know much about Honeywell; I’m just guessing. This post was last edited by matrixwhiz on 2009-3-8 at 17:51.]
I asked today, and it seems that it really isn’t supported; MODBUS is the only option available. TPS’s support for MODBUS also doesn’t seem to be very good. The communication speed seems particularly slow. It seems I’ll have to suggest that users upgrade their DCS, hehe
The communication between TPS and MODBUS should be fine! We use the TDC3000 to communicate with HIMA’s safe shutdown system, via the 485+MODBUS protocol, and there is no issue of slow performance!
HONEYWELL’s TPS indeed does not support DP communication; however, you can use MODBUS RTU for communication. For example, if you are using SIEMENS equipment, you can add a CP341 card. But HONEYWELL imposes certain restrictions on MODBUS RTU communication. Generally, there are no issues with dozens of analog input points along with a few hundred digital input points. I have implemented several similar solutions, and I have never encountered any problems related to slow performance.
