7 APPLICATION INSTRUCTION
7.21 Module access instruction
Writing 1-word/2-word data to another module (32-bit
specification)
TOD(P), DTOD(P)
• TOD(P)
These instructions write the (n) points of data in the device starting from the one specified by (s2) to the buffer memory
address specified by (s1) in intelligent function module specified by (U/H).
•DTOD(P)
These instructions write the (n) 2 points of data in the device starting from the one specified by (s2) to the buffer memory
address specified by (s1) in intelligent function module specified by (U/H).
■Descriptions, ranges, and data types
■Applicable devices
*1 Only the DTOD(P) instruction can be used.
