Internal error of the block. If there is no error, the value 0 is output.

Decimal value ERROR_STATUS

Description

350

Parameter LOCAL_DEVICE_ID is invalid.

360

Parameter LOCAL_PORT is invalid.

ERROR_TCON

Error code of connection setup. The standard error codes for the TCON function block are output.

0X8yyy error code of TCON block is passed.

COUNT_TCON

Counter for the attempts of connection setup. An increasing value indicates problems when establishing the connection to the ibaPDA computer.

ERROR_TSEND

Error code when sending. The standard error codes of the TUSEND block are output.

0X8yyy error code of TUSEND block is passed.

COUNT_TSEND
