To connect the Display
to MELSEC iQ-R/iQ-F, use the iQ-R/F Series Ethernet(SLMP Client)
driver.
In an environment where the Q/QnA Series Ethernet driver is already
being used, and only when you cannot add a new driver should you
use the Q/QnA Series Ethernet driver to connect the MELSEC iQ-R/iQ-F.
1:1 Connection
1:n Connection
Maximum number of External Devices is 64.
1:n connection (access beyond network)
You can access other stations via MELSECNET/H, MELSECNET/10, Ethernet, or Q Series C24 unit.
Maximum number of External Device is 64.
When communication over the network, set the timeout to a value greater than the relay station's response monitoring time.
When the relay station is iQ-R series, use units with firmware version 9 or later.
The iQ-F series cannot be used as a relay station.
Available devices and address ranges for an External Device that uses the network to communicate are limited to the devices and address ranges of the relay station.
When using the Ethernet interface module QJ71E71-100
on the connected station to access another station through the
C24 unit, make sure that the top five digits of the Ethernet interface
unit's serial number is 24032 or greater.
Additionally, when accessing other stations through the C24 unit,
the routing setting is required for the CPU unit of the relay
station.
For information on how to set up routing, refer to the External Device
manual.
Setting example for access outside the network are shown below.
| External Device to Access | Port No. | Station No. | Network No. | PC No. | Request destination module I/O No. | Request destination module Station No. |
| External Device (1) | 1025 | 5 | 0 | 255 | 1023 | 0 |
| External Device (11) | 1026 | 5 | 2 | 6 | 1023 | 0 |
| External Device (22) | 1027 | 5 | 3 | 8 | 32 | 15 |
