Programming Examples

The following are sample programs for entering data in the

configuration words of the write block transfer instruction when

using the PLC-2, PLC-3 or PLC-5 family processors.

To enter data in the configuration words, follow these steps:

Example:

Enter the following rung for a write block transfer:

400 is the address of the write block transfer data file. You want to

examine configuration word 1.

Use the above procedure to enter the required words of the write

block transfer instruction. Be aware that the block length will depend

on the number of channels selected and whether scaling is or is not

performed; for example, the block may contain only 3 words if no

scaling is performed but may contain 37 words if using 16 inputs

with scaling.
