Does anyone know if the Mitsubishi Q-Series MELSEC fitted with Profibus DP Master module QJ71PB92D supports co-existence of a Class 2 Master (such as SIMATIC PDM + CP5512 Softnet) on it's network? If so, how did you get it to work ?
We have been trying to connect Siemens SIMATIC PDM to access some Profibus PA Instruments (Siemens SITRANS Probe LU 12m and BEKA Field Displays) that are connected behind a Pepperl & Fuchs DP/PA Coupler (SK1 type KFD2-BR-Ex13PA93) which runs at 93.75kbits/s on DP side.
The DP side has about 6 nodes connected.
Strangely without the DP nodes in Cyclic comms it works but as soon as the DP nodes (Hach-Lange SC100 DO Analyser, Rotork Actuator, Siemens MAG6000 flowmeter, and a Flame detector via an Anybus-DP RS232/DP gateway) are brought into the project the PLC goes into Fault then STOP when PDM starts scanning the Profibus Network with its "Lifelist" function.
PDM is running on a laptop with Siemens CP5512 or CP5511, and also tried on Siemens Field PG with intergrated CP5611.
We made the following Profibus DP bus parameter settings advised by P&F for the SK1 to work properly ..
Tslot: 4095 tBit
Min Tsdr: 22 tBit
Max Tsdr: 1000 tBit
Tset: 55 tBit (although our PDM notes say 150 for this one)
Tqui: 0 tBit
Gap Factor: 10
Retry Limit 3 (although SI had this set to 1 in the PLC settings).
Ttr: 19968 tBit
