● This instruction is used for FBs-7SG1/FBs-7SG2 module’s application. It can convert the source
alphanumeric characters into display patterns suited for 16 segment encoded mode display or perform the
leading zero substitution of the packed BCD number for non-decoded mode 7 segment display.
● When execution control “EN” = 1, and input “OFF” = 0, input “ON” = 0, if Md = 0, this instruction will
perform the display pattern conversion, where S is the starting address storing the begin converted
characters, Ns is the pointer to locate the starting address character, Nl tells the length of begin converted
characters, and D is the starting address to store the converted result.
Byte 0 of S is the “1st” displaying character, byte 1 of S is the 2nd displaying character,…….
Ns is the pointer to tell where the start character is.
Nl is the character quantity for conversion.
After execution, each 8-bit character of the source will be converted into the corresponding 16-bit display
pattern.
● When input “OFF” = 1, all bits of display pattern will be ‘off’ if Md = 0. if Md=1, all BCD codes will be
substituted by blank code(0F)
● When input “ON”= 1,all bits of display pattern will be ‘on’ if Md = 0. if Md = 1, all BCD codes will be
substituted by code 8(all light).
● Please refer Chapter 16 “FBs-7SG display module” for more detail description.
