Startup Operation
After power is turned ON, approximately 1 s is required for the first conversion
data to be stored in the input word. During that period, the data will be 7FFE.
Therefore, create a program as shown below, so that when operation begins
simultaneously with startup it will wait for valid conversion data.
Handling Unit Errors
• CPM1A Expansion Unit/Expansion I/O Unit errors are output to bits 0 to 6
of word A436. The bits are allocated from A436.00 in order starting from
the Unit nearest the CPU Unit. CPM1A-TS002 and CPM1A-TS102 Tem-
perature Sensor Units are allocated two bits each. Use these flags in the
program when it is necessary to detect Expansion Unit/Expansion I/O
Unit errors.
• When an error occurs, the Temperature Sensor Unit data becomes 7FFF
hex (the same as for an open-circuit detection). With an open-circuit
detection, it is not reflected in word A436.
Programming Example

The following programming example shows how to convert the input data
from 2 temperature sensor inputs to BCD and store the result in D0 and
D1.
