ComfilePLC Product Concept

ComfilePLC is a SoftPLC that works on ComfilePi (There is no PC version or MCU version.)

Basically, it supports Rpi's GPIO, and supports Remote I/O that can be connected to i2c.

**

Then, We can have a new type of iot PLC that was not in the existing market is born.

  • PLC that allows online editing without going to the field
  • PLC that can be edited in the field without a laptop or PC
  • PLC that can be operated while viewing the NODE-RED Dashboard with a smartphone

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.

  • 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.
