OMRON SYSMAC Ethernet communication driver is the driver to communicate with PLC( ethernet module ) of OMRON Corporation in Japan.

1. Read Settings

<Figure 1> is read setting example of OMRON SYSMAC Ethernet communication driver.

<Figure 1>  Read setting example of OMRON SYSMAC Ethernet communication driver

Device part of  <Figure 1> input Device type(UDP/IP or TCP/IP), IP address of PLC(210.120.20.1), service port of UDP/IP ( or TCP/IP ) protocol ( 9600 ),respectively, according to setting of PLC.

In protocol option part, you can set CPU type( 0 = CS/CJ, 1 = CV, default = 0 ), Network address of PLC( 1 ~ 127, default = 1 ), Network address of computer( 1 ~ 127, default = 1), Node address of computer( 1 ~ 126, default = 100 ). Each argument  is a comma-delimited.

Note) Please refer to manual of OMRON PLC or chapter 3 for Network, Node address....

Note) You can set IP address and Node address by using 'Cx-Programmer'.

If don't matck IP address or Node address, “Write Not Possible”(Main Error = 21, Sub Error = 08) error will occur.

Also, “Command Format Error” will occur when 'Unit number' incorrectly set.

OMRON SYSMAC Ethernet communication driver read schedule

Read schedule setting parameters are as follows:

1) Unit number – PLC unit number( 0~47, ... ).

0 =  CPU Unit,  16 ~ 31 = CPU Bus Unit 0 ~ 15,  E1 = Inner Board,  FE = Unit Connected to Network.

2) Read memory type – memory type = CIO, WR, HR, AR, TF, CF, TIM, CNT, DM, EM0 ~ EMC, EM, EM_CURR, TKF, TK, IR, DR, CLOCK, CONDITION,... ( refer to <Table 1> )

3) Read start address – read start address in memory type.

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read size – read size. word memory area = 1 ~ 999, byte, bit memory area = 1 ~ 1980.

6) Unit of float data – 0 = word, double word unit, 1 = float unit.
