7.19 Clock instruction
Reading clock data
TRD(P)
These instructions read the clock data from the built-in real time clock in the CPU module.
■Descriptions, ranges, and data types
■Applicable devices
• These instructions read the clock data (SD210 to SD216) from the built-in real time clock in the CPU module to the device
numbers (d) to (d)+6 in the following format.
• The table below shows the related devices. The clock data stored in these special registers is updated during the END
processing.
