The FINS command system supports communication with devices on local and remote OMRON networks.
FINS tab
This Driver's properties window, in addition to several configuration options, also displays a selectable list with IDs of remote devices already configured. This list appears empty if there are no configured IDs.
To determine a list of IDs from remote devices, users must fill in correctly all options in the FINS addresses (PLC) group.
A device ID is a network address with 3 (three) layers, which uniquely identify a target device. The format of a device ID is AAA.NNN.UU, in which:
•AAA: FINS Destination Network Address (Network: between 0 (zero) and 127, in decimal notation)
•NNN: FINS Destination Node Number (Node: between 0 (zero) and 255, in decimal notation)
•UU: Number of the Host Link Unit used for the computer interface (Unit: between 0 (zero) and 31, in decimal notation)
The next options are available for manipulating data on the list of IDs:
•Add: Adds new parameters
•Update: Changes parameters already listed
•Remove: Completely removes a row of parameters
When adding a new ID to this list, it automatically receives an index. This index is then used to refer to this ID when configuring a Tag.
The Source addresses (PC) group refers to the configuration of the local computer and its options are configured the same way as the FINS addresses (PLC) group. The PLC Type option allows selecting the type of PLC to communicate. Possible values for this property are CS/CJ or CV.
The Ignore non-fatal CPU unit errors option can be selected if non-fatal error codes are returned by an equipment. It is normal for this Driver to consider every non-fatal error as an error, discarding the values received despite being indicated as data for a normal completion and not compromising the integrity of these values. When selecting this option, this Driver handles with less rigor and disregard the indication of non-fatal errors in a unit.
NOTE |
Information to fill in the Source addresses (PC) group are Network: Which must be the same as the Local PLC, Node: Which must be different from Local PLC's Node and different from 0 (zero), or Unit: Which is not used and it is recommended to leave it in 0 (zero). For communication via Ethernet with devices using the FINS protocol, the Transport option configured on the Ethernet tab must be equal to UDP/IP. For communication via Ethernet with devices using the Host Link protocol, the Transport option configured on the Ethernet tab must be equal to TCP/IP. |
