Programming; Read/Write Operation Of Operation Parameters Setting Area; Read Data From The Operation Parameters Setting Area (Get, Getp Instruction); Difference Between Get Instruction And Getp Instruction - Honeywell 2MLF-RD4A User Manual

6.1 Read/write operation of operation parameters setting
area
The instructions of GET, GETP are used to read data from special modules like the RTD
input module and save it in CPU memory.

Read data from the operation parameters setting area (GET, GETP instruction)

Operand
n1 Slot number where the special module is installed.
Start address of internal memory of special module to
n2
read.
Start memory address of CPU module where the read
D
data will be saved.
n3 Number of words (data) to read.

Difference between GET instruction and GETP instruction

GET: executes at every scan when execution condition is true ON. (
•
GETP: executes once at the rising edge of the execution condition. (
•
Example:
RTD module is installed on Base No.0 and Slot No.3.
The data from internal memory addresses 0 and 1 is in the RTD module and is read and
saved in D0 and D1 of CPU module while M00000 bit is turned ON.
