PS
：
a.
Relay/Coil module is digital module (DI/DO module), the unit is Byte;
Register module is analog module (AI/AO module), the unit is Word.
b.
Modbus Slave Device ID
：
It is a Modbus Slave device address.
c.
Start Address
：
The GW-7553-B / GW-7553-M and Modbus Slave device
exchange data from this starting address.
d.
NO. of Relay/Coil
：
It is data size that the GW-7553-B / GW-7553-M and
Modbus Slave device exchange.
e.
Module type
：
The user can select data type for data exchange by this
setting.
Write DO(WDO)-- Write Digital Output
Write AO(WAO)-- Write Analog Output
Read DI(RDI)- Read Digital Input
Read DO(RDO)- Read Digital Output
Read AI(RAI)-Read Analog Input
Read AO(RAO)-Read Analog Output
f.
Change Word Order
：
When this setting is “Enable”, the GW-7553-B /
GW-7553-M will change the data between the high word and low word for
reading easily.
g.
TCP_Connect_Index
：
The user can select TCP connection of the module.
The module will transmit and receive data from this connection.
4.5 Diagnostic messages
The GW-7553-B / GW-7553-M can record maximally 10 diagnostic messages at
the same time. If the number of the diagnostic messages is bigger than 10, the
GW-7553-B / GW-7553-M will not process other diagnostic message. The
diagnostic messages have four types. They are “Module Error”, “System Setting
Module Error”, “EEPROM Error” and “Input Data Error”. The diagnostic
messages are shown in
Table 14
.
