Reading module information
UNIRD(P)
Processing details
• Reads the module information as much as designated by n2 from the module designated by n1, and stores that information
into the area starting from the device designated by (D). (Reads the status of the actually installed modules even if the
module type and the number of points are changed by I/O assignment.)
• The details of the module information are described as follows:
n1: Value (0 to FFn) which the start I/O number of the module information read source is divided by 16 (BIN 16 bits)
(D): Head number of the devices where the module information will be stored (device name)
n2: The number of points of read data (0 to 256) (BIN 16 bits)
