APPENDIX 1.3 Replacement of special relays/special registers
When a project for Q173HCPU(-T)/Q172HCPU(-T)/Q173CPUN(-T)/Q172CPUN(-T)/
Q173CPU/Q172CPU is converted into a project for Q173DCPU/Q172DCPU using the
"Project management - File diversion" in MT Developer, special relays (M9000 to
M9255) and special registers (D9000 to D9255) are automatically converted into new
special relays (SM2000 to SM2255) and special registers (SD2000 to SD2255)
respectively.
However, in order to maintain the same functionality the user must manually convert
them to the special relays and special registers shown in Table 1.3 and Table 1.4
below for Q173DCPU/Q172DCPU.
