I am using NJ Omron driver in opcua devices to connect my PLC: nj501-1400，all connection settings are default. There is a bool array arr in PLC. When its length is greater than 941, there will be a value transmission error. In PLC, the value of arr [0] will be received by arr [8] of opcitempath in tag, a [1] will be received by a [16], and so on. I can’t find similar problems in the forum. Can you help me see what happened.
