Delay time
*note1)
100ms -
Operation
Reads present value and setting value from temperature controller every second and
saves present value at %MB200 and setting value at %MB210.
Note 1) Delay time is set to prevent from frame error when communication with device of which response is slow in case of
RS-422/485 communication. It varies according to partner device and it has 50~100ms value generally.
Note 2) Please refer to (http://hynux.com) for the communication setting of the Han-young temperature controller by user
manual.
