CODESET

  • Ladder diagram convert to mnemonic and then to make a codeset.
  • The codeset will downloaded to PLC and saved in EEPROM.
  • PLC MCU reads and executes the codesets in eeprom in sequence.

MATH

Mnemonic Code(Hex) Explain
+ 48(30) Add
- 49(31) Sub
* 50(32) multiply
/ 51(33) division
MOD 52(34) Mod
« 53(35) Bit Shift Left
» 54(36) Bit Shift Right

  • MATH has only one operator.Parentheses are also not allowed.
  • MATH D0 * 100 D2 Convert to 50 D0 100 D2
  • D0 = D1 * 2 also can use. (same as MATH D1 * 2 D0)
  • D0 = D1 * D2 * 2 (same as MATH D1 * D2 D0, MATH D0 * 2 D0) Parentheses cannot be used, Operates sequentially from the beginning without operator priority.

About C,T

When used in a function, C becomes CC, T becoms TC.

Symbol Original to CODE
–[ ] TON T1 100 166 21 198 1 0 19 100 00

When used in a input(BOOL) symbol, C becomes C, T becoms T.

Symbol Original to CODE
–! !– T1 250 1 0
