Fig. 3.9 Allocation of Output Coils
When allocating output coils, the MEMOSOFT is set by default to “MSB.”
When output coil allocation is set to “MSB,” the leading reference number is allocated
to the smallest output number (output 1) on the Output Module.
(2) When output register 400001 is allocated, the bit order can be set to either
“MSB” or “LSB,” as described in the following table and shown in the illustration
below it.
Refer to Fig. 3.10 Allocation Output Registers for details.
Fig. 3.10 Allocation Output Registers
When allocating output registers, the MEMOSOFT is set by default to “LSB.”
When output register allocation is set to “LSB,” bit 15 (MSB) of the output register is
allocated to the smallest output number (output 1) on the Output Module.
