3 Input/Output Signals with Machine
Classification of Machine Input/Output Signals
The signals handled by the PLC are classified as shown below.
When designing, refer to the section indicated below and make allocations according to the table in the respective section.
Signal type
DI Machine
PLC Switch Input(*1)
Input
Sensor input
AI (Analog Input)
DO Machine
PLC Switch Output(*1)  Output used to show that setting and display unit PLC
Output
AO (Analog Output)
(*1) The PLC switches are not signals for directly inputting/outputting with the machine, and are hypothetical switches used
by the user on the setting and display unit. When classified by property, they are as shown above.
IB-1501614-B
Explanation
 Allocated to device X.
 Some connector pin allocations are determined.
- Stroke end signal (+, -)
- Reference point return near-point detection signal
 The high-speed processing input is set with the parame-
ters. (Read in at the head of the high-speed processing
scan.)
 The switches can be substituted by the setting and display
unit.
 Allocated to device X.
 The switch names displayed on the setting and display
unit are user release switches. The names can be created
with the ladder message creation.
 Differs from other DI signals, and is connected to the con-
troller. This is only used for monitoring on the ladder side.
 The connector pin allocation is determined.
 Allocated to the file register (R).
 Allocated to device Y.
 The high-speed processing Output is set with the parame-
ters. (Output at end of the high-speed processing scan.)
switch input is valid.
 Allocated to device Y.
 The connector pin allocation is determined.
 Data to be D/A converted and output can be output by
reading it into the file register (R).
