MGate 4101-MB-PBS
Configuration
4-21
The first command is to read Modbus device’s command with function code 03 and the acquired data is to be
read by the PROFIBUS master; hence, these data are being placed at Input memory area. Therefore, we set I/O
type as Input, and with total 4 bytes data length. You may use data length of 2 with word data type or use data
length of 4 with Byte data type.
For the second command in the Modbus side showed above, the PROFIBUS master would write data to Modbus
device through gateway. Hence, we set PROFIBUS I/O Module with Output I/O type with 2 Word byte types.
The I/O Map shows as follows. See [ ] signs.
