Modbus Error Codes

Data Exchange

Introduction	During operations, you may encounter Modbus error codes that are returned by the
	STB NIP 2212 NIM to the Advantys configuration software. These error codes are
	displayed as byte codes in hexadecimal format.

	Note: Because the STB NIP 2212 NIM supports Modbus over a serial interface,
	the Ethernet-based Modbus server does not support Modbus requests with a unit
	ID of 255 (0xFF). In the PL7 programming tool, the default value for the field unit
	ID when adding an I/O scanner connection is 255 (0xFF). Be aware that the NIM
	drops packets with this unit ID.
