n1 The slot No. where a special module is mounted
Head address of the special module buffer memories from which
n2
the data will be read.
D Head address of the device to store the data read.
n3 Number of data to be read .
GET: Always executed if the execution condition turns on.(
GETP : Executed if the execution condition is triggered. (
Example 1) In this example, the PID control module is mounted on the slot 3 in the base unit and the data of
buffer memory addresses 202 and 203 will be read to the CPU module addresses D202 and D203.
