(3) Creating Ladder Program
(1) Write temperature data command
Write temperature data command which read temperature data from input word to CIO
n+1.
(2) Response confirmation
After CP1W-TS004 receives CIO n+1 read command and CP1W-TS004’s internally
specified input temperature data is ready, the value which is the same as the read
command will be stored in CIO m+1. The temperature data will be stored in CIO m+2
at the same time.
(3) Read temperature data
Store the temperature data from CIO m+2 in DM area.
Note 1
It takes about 2ms maximum until it is reflected to CIO m+1 and m+2 from writing the read command to
CIO n+1.
2
It takes about 1s after the power is turned ON, till a read command initial processing of CP1W-TS004 is
completed, so a response to the read command after power ON takes only about 1s. After the power is
turned ON, create a ladder program 1s later due to its control by temperature data.
3
When writing a command other than that specified in the temperature data read command, CIO m+1 and
m+2 hold the previous value.
The power is ON
CIO m+2
