T_CONFIG
– IN: REQ – with REQ = 1 starts processing of the instruction.
INTERFACE – Hardware identifier of the interface. Can be found in system constants, or device view
CONF_DATA – Pointer to the higher-level structure in configuration data block
– OUT: DONE – Status of completion
BUSY – Progress of operation
ERROR – Error state
STATUS – Detailed error and status information
ERR_LOC – Error location

Sub-field device IP length = 6 bytes (header) + 12 bytes (4 bytes IP address + 4 bytes Subnet + 4 bytes Router) = 18
Sub-field device name length = 6 bytes (header) + n bytes (1 char = 1 byte). Example: mainplc = 6 + 7 (‘m’ + ‘a’ + ‘i’ + ‘n’ + ‘p’ + ‘l’ + ‘c’) = 13
