Data Reading
When "Read" is set in the PLC Communication Settings (Device config), communication is performed
at the specified scan cycle and the obtained information will be set in Modbus memory.
Using PLC read data with "CONPROSYS VTC" can be realized by referring to the information set in
Modbus memory. How to refer to the PLC read data with "CONPROSYS VTC" is explained here.
The "Input Modbus" is used to obtain Modbus memory.
- Input Modbus
Assign the specified Modbus memory information to TAG.
TAG[xx] = Modbus memory
* TAG : Variables used in the CONPROSYS
- Property
Property Name
Default
Description
TAG ID
TAG00
Specify TAG (variables) to assign the Modbus
memory information.
Modbus address (Dec)*1
Modbus address (Hex) *2
Fixed value
Specify Modbus memory address to refer to.
Specify the offset value from 2000h.
The specification method (decimal / hexadecimal)
differs depending on the firmware versions. *1,*2,*3
Size (the number of tags)
Fixed value
Specify the access size in decimal. *3
Data type
Unsigned data
(16-bit)
Specify the data type to enter in TAG.
Signed / Unsigned and 16-bit / 32-bit are available.
Word order
Displayed only when the data
type is selecting 32-bit.
Little endian
Little endian : The specified address is used as the
lower word.
Big endian : The specified address is used as the
upper word.
*1 Specify in dec : V1.20 or later versions / Gateway Firmware V2.6.0 or later versions
*2 Specify in hex : V1.19 or earlier versions / Gateway Firmware V2.5.1 or earlier versions
*3 Specifying with variables (TAG) is also available in addition to the fixed value.
