and the 2nd [or more] figure is written with the number of decimal.
- The devices (V, I, Q, M, SM, S) which include a period in the address in S7-200 are written without a period in MICRO/I.
For example, V10.1 is written as V101 in MICRO/I.
AC (Accumulator registers), L (Local memory) of PLC Devices can not use in MICRO/I.
- The value of High speed counter which is a double word value is divided into two, and is treated as WORD device in
MICRO/I.
The higher word is written by adding 0 to the lowest digit of the address, the lower word is written by adding 1 to the
lowest digit of the address.
For example, the lower word of HC1 is written as HC11 in MICRO/I.
If you read in a double word value, The lowest digit of the address write 0. For example, HC2 is written as HC20 in
MICRO/I.
