I am using a 1510SP CPU to communicate with a cloud-based MQTT broker using the blocks from Libraries for Communication for SIMATIC Controllers. The hwid variable in the LMQTT_typeConnParam structure specifies the Ethernet port that the block should use for MQTT communication. If I specify 0 for the hwid, the block connects to my MQTT broker. However, I plan to add a CP module for cloud communication, so would like to be able to specify the Ethernet port used. At present I am testing using the CPU's Ethernet port. In the PLC Tags / System Constants, Local~PROFINET_interface_1 is set at 64. However, If I set hwid to 64, I get a 16#809B error from TCON, indicating that TCON doesn't think that the interface ID is valid. I have tried other values for hwid, but the only one that doesn't throw an error is 0. Has anyone found a hwid value that TCON will like on a 1510SP/1512SP? |
