MODBUS TCP Communication between 1500 PLC and Schneider Frequency Converter ATV630 with PROFINET Interface
1. In order to communicate with the converter with the function block in MODBUS TCP, besides using MB_SERVER as the step in Quick Start, is it necessary to do a cyclic program to write and read data with the converter periodically?
2. Does the MB_SERVER function block contain the functions of writing and reading data?
3. Are the two function blocks MB_CLIENT in MODBUS_TCP, TSEND_C, TRCV_C and TMAIL_C in MB_SERVER and open user communication all MODBUS TCP communication, which way is all right?
4. With the block in the open user communication, we have to write periodically. Read the program, right?
5. I have 6 converters on site to communicate. Is there enough connection resources? CPU is 1515-2PN
