Listed below are the steps to program the Read from Intelligent module function.
Step 1: Load the base number (0-3) into the first byte and the slot number (0-7) into the
second byte of the second level of the accumulator stack.
Step 2: Load the number of bytes to be transferred into the first level of the accumulator stack
(maximum of 128 bytes).
Step 3: Load the intelligent module address which will receive the data into the accumulator.
This parameter must be a HEX value.
Step 4: Insert the WT instruction which specifies the starting V-memory location (Vaaa)
where the data will be written from in the CPU.
Helpful Hint:
S
Use the LDA instruction to convert an octal address to its HEX equivalent
and load it into the accumulator when the HEX format is required.
NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the WT instruction will write six bytes of data to an
intelligent module in base 1, slot 2,starting at address 0 in the intelligent module, and copy the
data from V-memory locations V1400-V1402.

Write to Intelligent Module (WT)
The Write to Intelligent Module instruction writes a block of data
(1-128 bytes maximum) to an intelligent I/O module from a block
of V-memory in the CPU. The function parameters are loaded
into the first and second level of the accumulator stack and the
accumulator by three additional instructions.
