WRITE Write data to the shared memory
of an intelligent I/O unit
Double words
Ladder
WRITE: Read NR3 words from NR5, and write them to slot
NN1, module memory address NR2.
Description
1. NN1: Slot number of the intelligent I/O module to write to. The first slot in the backplane is
slot 0.
NR2: Starting address to write to on the shared memory of the intelligent I/O module
(number/register).
NR3: Number of words to write (number/register).
NR5: Starting address of the data to write (number/register).
2. This instruction is used to write data to the shared memory of an intelligent I/O module such
as the high-speed counter, SDU module, analog module, or position control module. Refer to
the specific intelligent I/O module user's manual for detailed instructions on using the WRITE
instruction with the given module.
3. If the NR5 parameter is a constant value instead of a register address, then this constant value
will be written to all of the shared memory locations specified. This function is useful for
initializing the shared memory of an intelligent I/O module.
4. This operation will occur on every scan for which the input condition is true (On). To perform
the operation only on a change of input condition, use the rising/falling edge contact.
