Troubleshooting

Use the following chart for assistance in troubleshooting the Modbus Adapter; the chart
contains the most common faults and corrective actions.

Table 58: Troubleshooting Chart

Observation Possible

Cause/Action

None of the LEDs are
illuminated

Verify that power (24 VDC) is applied to the Modbus
terminal and that power is on the QCPort channels.

Verify that all devices on the QCPort ports are set to
unique addresses.

Verify that you are holding the Configure button for the
required 5 seconds

IO Configuration will not
complete

Power cycle the Modbus Adapter and QCPort devices.

The data in the Modbus
input assembly is all zero’s

Verify that the Scan Active bit in the Modbus register
2049, 2050 or 1025 is set to one.

Cant auto configure QCPort
or cant see any devices on
QCPort

Verify that QCPort has a biasing resistor installed such as
the D77E-QPLR or the D77E-TERRJ.

Unit ID

1 (always 1 but can be changed)

IP Lost

Use Studio to rediscover the device

Power Up Reset

Not scanning

Is scan enabled in register 1025

Controller cant see after
setting IP address

Check subnet mask

Can communicate over
Serial Modbus RS485

Verify valid range, 1 – 246
