Unit 3 Read Data Area
(SYSWAY)
The segment information is 1 and the command group is 1.
Note The entire Unit 3 read data area is refreshed even though command group 1
is selected and only the values in DM 0240 to DM 0242 are read from the
component. (The contents of DM 0244 to DM 0250 are cleared to 0000.)
When communicating with a Temperature Controller through SYSWAY,
always allocate 11 words to the read data area even if the selected command
group limits the number of words actually read.
Unit 3 Write Data Area
(SYSWAY)
The segment information is 1 and the command group is 1.
Note It is possible to write just the target temperature by selecting command group
1.
When communicating with a Temperature Controller through SYSWAY,
