About devices when using Virtual-M3
Virtual-M3 devices have the same types and device points as the sequence CPU module, except for special relays and special registers.
For details on supported special relays and special registers, refer to the Virtual-M3 manual.
High-speed communication devices
In addition to the devices listed in the device list, there are devices with "F" at the beginning of the device name that can actually be selected (FX/FY/FI/FL/FM/FD/FB/FR/FV/FZ/FW/FF). These are high-speed access devices that can communicate large numbers of points at high speed. For example, "FX" is an input relay and "FD" is a high-speed communication device for a data register. However, writing to high-speed communication devices in bit units is treated as "●". Also, even within one packet of communication, it is asynchronous with the scanning of PLC. Although the synchronism of scanning data in units of 1 word (16 bits) is guaranteed, the synchronism of scanning with adjacent data is not guaranteed (care must be taken when handling as 32-bit data).
Example of communication time per read when reading 5000 data registers at once
For FD: 230ms
Case D: 1243ms
|
High-speed communication devices only support "binary mode." In addition, communication may not be possible depending on the model. The following devices have been confirmed to work with our company. ・LE01-5T ・LE01-OT (*Can communicate other than FX/FY) ・LE11-1T |
Driver Selection
Please select the driver according to the model you are using.
•For FA-M3R/FA-M3V, select the "FA-M3R/FA-M3V (Binary Mode)" driver.
•If you are using the older FA-M3, select "FA-M3 (Binary mode)."
If you need to set the communication protocol to "ASCII mode" due to compatibility with other devices, select "FA-M3 (ASCII mode)." The ASCII and binary mode settings on the FA-M3 side are set using the dip switches on the Ethernet unit.
* "FA-M3 (Binary mode)" and "FA-M3 (ASCII mode)" can be used with FA-M3R/FA-M3V. However, please note that communication speed will decrease when communicating a large number of points.
