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.

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.
