Device can be added using context menu of the node.
The added device represents a user configurable device. FX5 - new Mitsubishi controllers, FX3 is an old series - a special Ethernet module is required to work with the SLMP protocol.
The device FX5 contains 3 additional properties located in "Protocol properties":
Destination Network - remote network address. By default - 0.
Destination Station - remote device address. By default - 255 (0xFF).
Destination Module - remote module address (station, CPU, reserved CPU and etc.). Default address - 1023 (0x03FF - Own Stantion).
Destination Network, Station and Module default settings are selected for direct polling of a fixed PLC without redundancy, in other cases may be required to modify these settings. Parameter values can be found in the official manuals for the SLMP protocol.
Maximal admissible interval between addresses in read request – maximal admissible interval between addresses in one read request. For example, registers 0, 1, 2, 4 and 5 are requested. If the parameter equals 0, two requests are formed to poll the registers (0-2, 4-5). If the parameter is equal to 1 or greater, one request is formed to poll the registers (0-5, and the unused register 3 will be ignored when analyzing the reply). Increasing the parameter decreases number of requests and speeds the poll up but makes the reply frame longer.
The FX3 device contains one additional setting:
Max count registers in request - maximum number of registers in one read request. The default value is 50.
By default device contains an undeletable tag Failure in Diagnosis group: this tag becomes True when connection with device failed.
User tags can be added manually or by importing them from files created in GX Works 3.
