Hi All,
I'm currently working on a project with some fuji drives (frenic mini) and a micro850. Communication is through Modbus RTU. I don't have much experience with modbus rtu, but I have a general understanding of it. I'm curious if anyone here knows if the MODBUS_MSG in CCW handles the CRC automatically. I ask this, because in all the available datatype fields related to the modbus_msg I don't see any that seem relevant to CRC. If you choose the CIP serial option in the controller settings, there is an option below that for CRC (or BCC), but there is no option like that when modbus rtu is selected. Can anyone please chime in here? Regardles, I would love to talk to anyone who has successfully worked with the micro800 series and drives communicating via Modbus RTU to bounce a few questions around. Thanks in advance!
