About SCON-LC Type
■
(Only for Types up to 750W)
LC Type is equipped with a built-in PLC feature, and is capable to control SCON with ladder
programs instead of the host PLC if the programs are in small scale.
● PIO Type
Each signal of PIO is general input and output. Use it with connecting to internal relay, which each
IO pattern is assigned to, with the ladder program if necessary.
SCON-LC/LCG
● Fieldbus Type
Each bit in fieldbus communication is general input and output. Use it with connecting to internal
relay, which each IO pattern is assigned to, with the ladder program if necessary.
SCON-LC/LCG
For fieldbus communication, the data volume transferred in one time of communication is restricted.
For CC-Link
(1 station 1 time : Remote device station)
For those other than CC-Link
(Input 8 bytes, output 8 bytes)
