Modbus Rtu Tcp/Ip - KEP MMI-1500 Installation & Operation Manual

16.32 MODBUS RTU TCP/IP

16.32.1 HMI Setting – Ethernet port hardware option must be present
Communication parameters must be set the same as those of the PLC. The following settings are recommended.
Parameter
Serial I/F port
HMI station No.
PLC station No.
Comm. delay (10msec)
Multiple HMI
Connect I/F
Local IP address
Server IP address
Subnetwork Mask
Default Route IP address
16.32.2 PLC Setting
PLC ID number must match setting in MMI
16.32.3 Wiring
Use the same wiring as the MODBUS RTU driver. CAT-5 class through cable to Hub or crossover cable to Controller.
16.32.4 Device address
Bit/Word Type Address Format
B 1x
B 0x
B 3x_bit
B 4x_bit
W 3x
W 4x
W 5x
Note: The Controller's memory range may vary within the range supported by the driver. Use appropriate addresses.
NOTE:
Address type "5x" is mapped to 4x Internal Registers. 5x register types are the same as "4x" except "5x" double word data
is swapped.
For example,
If 4x has the following information
Address 1
Data in word 0x123
4x Data 0x2670123
For 5x, it becomes
Address 1
Data in word 0x123
5x Data 0x1230267
