MODBUS TCP

2.4.1

MODBUSTCP-05 Accessory

Connector

The Modbus TCP communication module has a standard female RJ45 connector (T-568A or T-568B).

Indications

Modbus TCP defines two LEDs for status indication: one for the communication module (MS) and another for
the network (NS).
The MS LED indicates the conditions of the module itself. That is, whether it is able to work or not. Table 2.14
shows the possible states:
LED Status
Off
Green
Red
Flashing red
Flashing green/red
The NS LED indicates the conditions of the Modbus TCP network.

Equipment performing self-diagnosis
Table 2.16: Status of the connection
Description

Activity in the bus
Comments
Internal error of the module. Equipment must be
reinitialized.
Internal error of the module, but the return to the
normal state occurs automatically after the cause of
the fault is corrected.
Check the IP addresses in the network.
It occurs during initialization.
The software IPconfig must be used to configure the
communication module address.
Equipment must be reinitialized to exit the fault state.
Check the IP addresses in the network.
The data exchange has been interrupted.
It occurs during initialization.
Comments
Without connection, without activity
Ethernet link established but without data exchange
between master and slave.
It effectively indicates that there is data exchange
between the master and the slave.
