PLC: V1210, Hardware: A, OS v3.4, Boot Ver: 2.2(11), BinLib v0-3.10(03), Factory boot: 1.3(07)
Win10 connecting works fine, android - sometimes, IOS - never. all are connecting through VPN. do get a message:
unitronics operand start address and end address must be non-negative and less than the operand count on the PLC
Any help would be appreciated!
