Overview

Module Description

The Modbus TCP (MBTCP) Gateway Module provides a control link between a Modbus TCP fieldbus and a sys- tem that uses Graco Control Architecture (GCA). This link provides the means for remote monitoring and con- trol by an external automation system.

Data provided by the MBTCP Gateway Module to the fieldbus depends on the GCA-based system. Mapping of Modbus registers is loaded by the host GCA system and varies by system.

Data Exchange

Data is available by block transfer or by explicit access to individual attributes as defined by the fieldbus specifi- cation.

Module Status LED Signals

Signal	Description

Green on	The system is powered up.

Yellow	Internal communication is in prog-
	ress.

Red	MBTCP hardware failure
Solid

Red Flashing	The red LED (F) will flash a code,
	pause, then repeat. See MBTCP
	Module Errors on page 7 for
	details.

3 flashes	The host device of the mapped
	property is not responding.

4 flashes	No valid mapping is set by the
	host.

5 flashes	MBTCP is not connected or the

	configuration.

NOTE:

If you get a “No Valid Map” error, disable and re-enable your gateway from the host device.
