AlexUT Posted June 17, 2019 Report Share Posted June 17, 2019 Hi, 1. You can use MODBUS protocol, if you find it (or write it) for Arduino. 2. Download Unitronics PCOM Protocol description from next link: https://unitronicsplc.com/Download/SoftwareUtilities/Unitronics PCOM Protocol.pdf This protocol used for VisiLogic to PLC communication.
