Modbus debug tool (Modscan32) instructions

Set the data bit to 8 bits, stop bit to one bit, and use the Modbus collection window below

Collect the intelligent number display instrument class:

If the measuring value of the collection PV is entered 010400000001? The collection HIAL value is input 010300010001?

Through and so on ...

Collect the intelligent PID regulator instrument class:

If the measuring value of the collection PV is entered 010400000001? The collection SV value is input 010300000001?

Collect the measurement value of the inspection instrument:

Enter 010400000001 to collect the value of the first road? Enter 010400000002, that is, the value of the first two roads input 010400000003, and the value of the first three roads, and so on!

Common problem

1. Connection problem

Unable to connect to the machine equipment

reason:

The settings of communication parameters such as Potter rate, data position, stop position, and verification are incorrect.

Error setting from the device ID (Device ID).

The external connection line is loose or damaged.

Solution:

Check and confirm that the communication parameter settings in Modscan32 are consistent with the machine equipment.

Confirm that the installation address settings are set correctly.

Check whether the external connection is firmly connected without damage.

MODBUS Message Time-OUT

reason:

Network delay or unstable.

The machine equipment is not responded or responded to timeout.

The communication protocol between Modscan32 and the machine equipment is not compatible.

Solution:

Check whether the network connection is stable.

Try to restart the machine equipment.

Confirm that the communication protocol (RTU or ASCII) settings between Modscan32 and the machine devices is correct.

2. Data reading and writing problems

Data reading is inaccurate

reason:

The register address or data type settings error.

Internal faults or data abnormalities from machine equipment.

Solution:

Check and confirm that the register address and data type settings in Modscan32 are correct.

Try to use other MODBUS debugging tools for verification.

Check whether the device runs normally and whether the data is accurate.

Unable to write data

reason:

From machine equipment does not support writing operations.

Write authority settings error.

The written data format or range does not meet the requirements of the machine equipment.

Solution:

Confirm the support of the equipment support from the machine equipment.

Check and revise the settings of the access authority.

Make sure the written data format and range meet the requirements of the machine equipment.
