| Using Shimaden Modbus Controllers |
To Setup Controller:
Set Protocol to MOD_RTU.
Data 8 Bits
Parity None.
Unit Number to suit.
Memory Locations
When accessing data, the addresses provided in the comms protocol are actual memory addresses, thus one may need to be added depending on the RTU driver you are using.
Example addresses:
| Address | Param | Modbus Address |
| 0100 | PV | 40256 or 40257 |
| 0101 | SV | 40257 or 40258 |
| 018c | WRITE COM (0=LOC,1=COM) | 40396 or 40397 |
| 0300 | Write SV* | 40768 or 40769 |
For using with MicroScan RTU driver, the +1 addresses are used (PV=40257)
* COM must be written first to write any data to the controller.
Testing:
A FP23 and SR90 have been tested with the MicroScan RTU driver.
