EtherCAT to Modbus RTU Gateway
The M-7050 module is used as an example, it support seven event counters. The commands [03] to
[16] that read these seven event counters cyclically. If the bit0 to bit6 of OutRxPDO[01] is rising, the

The address mapping of these 7 event counters are given as follows:
