1. Data notification is provided in order, from the leftmost digits to the right-
most. When reading data with the program, be sure to read it in that same
order.
2. Taking the Programmable Controller's cycle time and the communications
time into consideration, lower the reading cycle to 125 ms or less. If the
reading cycle exceeds 125 ms, normal data cannot be read.
The following program is an example of using the Temperature Input Terminal
in the display mode for 2 digits below the decimal point.
Settings
Temperature Input Terminal's allocated words: 350 to 353
Temperature Input Terminal's mode: Two digits below decimal point (DIP
switch pin 10: ON)
Operation
The temperature data from the Temperature Input Terminal's input 0 is stored
in words 30 to 32 in binary data multiplied by 100, as shown below.
