Example Application
Unit 2 Read Data Area
(SYSWAY)
Unit 2 Write Data Area
(SYSWAY)
The segment information is 1 and the command group is 1.
Word
DM 0200 Response monitor area
Contains 0000 when component communications are normal.
DM 0201 Present temperature
Contains the PV in 2's complement signed binary format.
DM 0202 Status
Contains the status when the PV was read.
DM 0203 Target temperature (See note.)
Contains the target temperature in 2's complement signed binary format.
DM 0204 Alarm 1 SV (See note.)
Contains the alarm 1 set value in 2's complement signed binary format.
DM 0205 Alarm 2 SV (See note.)
Contains the alarm 2 set value in 2's complement signed binary format.
DM 0206 Proportional band (See note.)
Contains the proportional band setting in binary.
DM 0207 Reset time (See note.)
Contains the reset time setting in binary.
DM 0208 Derivative time (See note.)
Contains the derivative time setting in binary.
DM 0209 Heater current monitor (See note.)
Contains the heater's electrical current in binary.
DM 0210 Heater current status (See note.)
Contains the status when the heater's electrical current was read.
Note The entire Unit 2 read data area is refreshed even though command group 1
is selected and only the values in DM 0200 to DM 0202 are read from the
component. (The contents of DM 0204 to DM 0210 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.
The segment information is 1 and the command group is 1.
Allocate words DM 0220 through DM 0228 to the Unit 2 write data area. In this
example data isn't written to Unit 2, so it isn't necessary to set data in the Unit
2 write data area.
