Overview

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

NOTE:

If you get a “No Valid Map” error, disable and re-enable

your gateway from the host device.

Module Requirements

Power Supply

The MBTCP Gateway Module requires a 12-30 VDC @

0.2 A power supply. Refer to the system manual for sys-

tem level power supply guidelines.

Environment Conditions

Refer to the system manual for guidelines regarding

environment conditions for the MBTCP module.

MBTCP hardware failure

Red Flashing The red LED (F) will flash a code,

pause, then repeat. See MBTCP

Module Errors on page 8 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

system has an invalid network

configuration.

Installation

334183B 5

Installation

The MBTCP Gateway Module is available for use with

all GCA-based systems that have a compatible design.

Each MBTCP module requires the following to operate

in a system:

• Mounting hardware

• Compatible GCA system

Install the MBTCP module as explained in the system

operation manual or in the installation kit manual.

If the MBTCP is offered only as an accessory for your

system, see Accessories in the system operation man-

ual for available MBTCP kits.

Install or Update Software

NOTE: The fieldbus connection is temporarily disabled

during the installation or update of software.

1. Ensure system is inactive.

2. Remove access cover (E)

3. Insert and press software token (T) firmly into slot.

4. Press the reset push button (M) once. Wait for red

light (L) to stop flashing. This may take up to 30 sec-

onds

5. Remove Token (T). Store in a safe place.

6. Replace access cover (E).

Connect Cables

Connect cables as explained in the system operation

manual.

FIG.3

NOTICE

Route cables to avoid interference with moving

parts.

Installation

Rotary Switch

If your system has only one MBTCP module, keep the

rotary switch (S) at its default position of 0.

If the system has multiple MBTCP modules, use a

unique value (position) for each module. Remove the

access cover (E) to set the rotary switch (S) for each

module.

Troubleshooting

Troubleshooting

MBTCP Module Errors

Module errors are triggered by overall system operation. The module status LED blinks red at a frequency of 1 Hz.

The red LED (F) will flash a code, pause, then repeat.

Module Status LED Signal Diagnosis Solution

3 red flashes The host of the mapped property is

not responding.

Check whether all system devices

are powered on.

Check cabling between all system

devices.

4 red flashes The host device (ADM) has not initi-

ated property mapping.

Disable and then re-enable the gate-

way module from the host device

(ADM).

5 red flashes The MBTCP module is not con-

nected.

Verify that the MBTCP module is con-

nected.

The system has an invalid network

Configuration.

Verify the proper network Confiugra-

tion.

Solid Red Gateway has been downloaded with

unsupported software.

NOTE: Does not apply to legacy sin-

gle port hardware. (See Fig. 5)

Check your gateway to ensure it has

software version 2.01.001 and up.

Troubleshooting

Modbus Errors

Modbus errors are typical protocol errors defined by fieldbus specification. The fieldbus error code shown is returned

to the PLC when the error condition occurs.

Code Name Cause Solution

1 Illegal Function Request function is not supported. Use supported Modbus functions:

• Read Holding Register

• Write Holding Register

• Write Multiple Holding Registers

2 Illegal Data Address Exceeded maximum register count

of 121 registers.

Request 121 or fewer registers at a time.

No valid property mapped to the

requested Modbus register.

Verify that the device has valid mapping.

See MBTCP Modbus Error for 4 red

flashes.

Write Holding Register(s) returns

set property error.

Verify that the end device is online.

3 Illegal Data Value Not implemented.

4 Slave Device Fail Not implemented.

5 Acknowledge Not implemented.

6 Slave Device Busy Not implemented.

8 Memory Parity Error Not implemented.

10 Gatweay Path Unavailable Not implemented.

11 Gateway Target Fail An active system error exists. Refer to system errors table.
