Format Description Available Data Type
n1 The slot No. where the specific modules mounted Integer
n2 Head address of the specific module buffer memory from
which the data will be read.
Integer
D Head address of the device to store the data read. M,P,K,J,T,C,D,#D
n3 Word number of data to be read. Integer
<The difference between GET and GETP>
GET: always executed if the execution condition turns On.( )
GETP : executed if the execution condition is triggered. ( )
Example 1). In this example, the thermocouple input module is mounted on the slot 3 in the unit and the
data of buffer memory addresses 17, 18 and 19 will be read to the CPU module addresses D17, D18 and D19.
