Fig. 3.6 Allocation of Input Registers
When allocating input registers, the MEMOSOFT is set by default to “LSB.”
When input register allocation is set to “LSB,” bit 15 (MSB) of the input register is
allocated to the smallest input number (input 1) on the Input Module.
b) Input Data Type
If an input register is set as the I/O reference number, data input can be set to binary
(BIN) or BCD. The MEMOSOFT is set by default to “BIN.”
c) Service Scan: Normal/High-speed
Two types of service scans are available: normal and high-speed. A service scan
is recommended when using the high-speed segment function. The I/O Module is
activated before the ladder decoding of the high-speed segments. The I/Os that are
processed in synchronization with the high-speed scan are called High-speed Seg-
ment I/Os. The MEMOSOFT is set by default to “NORMAL.”
