How can I create a second Modbus TCP connection if the third-party device only accepts one?In the AS PLC's Modbus TCP data exchange table, each configuration creates a single connection. If the third-party device only supports a single Modbus TCP connection, the AS PLC will be rejected if it attempts to establish a second one. To resolve this, upgrade the firmware to version 1.12.50 or later and enable the SM1037 flag. With this flag enabled, the PLC will generate only one TCP connection and send Modbus commands in order.
