For easy integration of this driver into the application it is handy to use: Preconfigurations in group "Omron PLC"
|TCP/UDP port number||9600 (default). Can be changed.|
|Ethernet transfer type|
TCP - Designed for FINS TCP type.
UDP - Designed for FINS UDP type.
|Protocol data type|
FINS TCP - Use this type if:
- the FINS nodes are connected through several IP layers
- the connection quality is poor (for example for wireless LAN)
FINS UDP - Use this type if:
- the FINS nodes are connected to the same Ethernet segment (FINS UDP provides higher bandwidth)
- the remote device does not support FINS/TCP
|Source Network Address||Number of FINS network where the PROMOTIC application is located. If the network contains only a single Ethernet layer then enter 0.|
|Source Node||Number of PROMOTIC application node (PC identifier) in the FINS network. The preset value is 253. If using FINS TCP or entering the value 0 then the PLC assigns the value automatically.|
|Source Unit||Formal number of the PC program (PROMOTIC). Typical value is 0.|
|Destination Network Address||Number of FINS network where the PLC communicating with the PROMOTIC application is located. If the network contains only a single Ethernet layer then enter 0.|
|Destination Node||Number of PLC node (PLC identifier) in FINS network. The value is configured by jumpers on the PLC. The FINS network topology allows to have one or multiple FINS nodes behind a single IP address.|
|Destination Unit||Number of logical unit of the PLC (parts). The OMRON PLC can be logically divided into several parts (units). The typical parts are the CPU, internal bus, perifery unit, communication module, memory of different types, etc. If a compact PLC is used then the value is 0, otherwise follow the device documentation.|
All variables are read (if the Data refresh enabled configurator is enabled). When writing to the variable, only the single value is sent (if the Auto write when writing to item configurator is enabled).
For all areas (except for TK and TKS) the "index" represents an array of values of 16-bit registers (W data type). Even if the 32-bit data types (L and R) are used then the "index" defines the index of lower 16-bit registry. The ItemID identifier can (but also may not) contain the specification of forced data type (b, I, L, R).
ItemId is the text identifier of the item that is used for addressing the value in the device. The ItemID configurator tells the driver how to receive or send the item value. The text can be written manually, or it can be assembled in the window opened by the button to the right of the configurator. Macro expression can be used for input (it is evaluated while the application is launching).
