Hi guys, I have a modbus network composed of two slaves. One at address 231 which initializes when the communication starts, and from which i can read and write data to. After RD/WR to this station, i need to read 16 input registers from the second station at address 1. If I force the slave address in the Modbus_MSG block, it doesn't work, because the slave address is set via a network at the start of the routine, and also has something to do with the memory pointer or something... :( Can you guys help me figure out how to reinitialize the serial communication for the slave at address 2, and allocate it a memory table ? The setting of the address was done by a colleague that no longer works with us, and cannot help me figure out how he designed the logic. I am attaching the .mwp and the .p14 (HMI) for the program in the hopes someone can shed some light on this problem. Attachmentproject.zip (210 Downloads) |
