Goals and Symptoms

communcation on Modbus with aTS46 We have a site comprising several ATS46s communicating with TSX Premium master. The communication protocol is unitelway.But one of the ATS46s has failed and we have to replace it by a ATS48.But ATS48s only communicate via modbus which means that we need to change communication protocol of other ATS46s with modbus.So,my question is,how can we change the com. protocol of ATS46 from unitelway to modbus?Do we need the ATS software or the panel is sufficient? Or does it recognize the protocol automatically? Best Regards,
