I have a Telemecanique SR1 B201BD smart relay that I would like to program. I have downloaded and installed ZelioSoft2 V5.1. I will be connecting my laptop up to it via the SR1 CBL01 serial cable. I am currently running Windows 10 as my host PC, but have VMs all the way back to XP in 32 and 64 bit varieties. Now when I try to communicate or transfer, I get an error "DC46_10" which describes possible solutions such as com port already in use. I have search around and have found two conflicting answers about ZelioSoft2 and its ability to program SR1 smart relays. On Schneider's website it says ZelioSoft2 can program SR2/SR3 smart relays, but other forums like this one say it can also program SR1. If it can not program SR1 smart relays, where do I find ZelioSoft1 or whatever programming software is required to program this smart relay.
