The FINS command system supports communication with devices on local and remote Omron networks.
FINS tab
The properties window of this Driver, in addition to several other configuration options, also displays a selectable list with identifiers of remote devices already configured. This list appears empty if there are no configured identifiers.
To determine a list of identifiers from remote devices, users must fill in correctly all options in the FINS addresses (PLC) group.
A device identifier is a network address with 3 (three) layers, which uniquely identify a target device. The format of a device identifier is AAA.NNN.UU, in which:
•AAA: Address of a FINS destination network configured in the Network option, a value between 0 (zero) and 127
•NNN: Number of a FINS destination node configured in the Node option, a value between 0 (zero) and 255
•UU: Number of a Host Link unit used for the interface of a computer, configured in the Unit option, a value between 0 (zero) and 31
The next options are available for manipulating data on the list of identifiers:
•Add: Adds new parameters
•Update: Changes parameters already listed
•Remove: Completely removes a row of parameters
When adding a new identifier to this list, it automatically receives an index. This index is then used to refer to this identifier 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 device 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 a device. 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: Must be the same as the local device, Node: Must be different from local device's node and different from 0 (zero), and Unit: 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. |
