Configuring and using
- 1. Create and start a logical controller object or use any present one with need scheduling properties.
- 2. Create a logical parameter object and select this template for it, one for each the devices — enable the parameter.
- 3. Into the tab "Template configuration" of the logical parameter object you need to set:
- Transport — to the address of the automatically created transport with its parameters after ":", according to the function SYS.Transport.outAt() address format.
- Device address [0...247] — set here the device address.
- ModBus type (for the logical controller object) — to the ModBus protocol type/variant from the list — RTU.
- ModBus maximum block size (for the logical controller object) — to the ModBus protocol package data maximum size in the range [10...200] — 200.
- ModBus blocks merging (for the logical controller object) — for allowance of merging the ModBus protocol fragmented blocks of the registers — 1.
- 6. RESULT: The logical parameter object will: dynamically create needed attributes accordingly to the attribute "Items set" value and perform interaction and placing of gathered data to the parameter attributes. Also you are able to change writable attributes.
