Analog value address conversion
S7-1200 analog addresses are set during the STEP 7 Basic device configuration. These
addresses are configured as part of the analog I/O device configuration. Analog value
addressing in the S7-1200 uses I and Q memory addresses. The following table lists the
default address ranges that are assigned to analog values converted from a STEP 7-
Micro/WIN program. You must configure the S7-1200 analog I/O to use these addresses or
substitute other addresses.

Converted S7-1200 memory address
S7-200 timer symbol names are converted to
S7-1200 timer DB names. S7-200 timer
output bit addresses are converted to a Q bit
address, in the timer DB.
If a S7-200 timer PT (Preset Time) input is a
WORD constant, then the program value is
not converted, for example "100" for PT on
T32 means 100ms. You must convert the S7-
200 program value to the equivalent S7-1200
TIME data format, for example "T#100ms",
"T#59s999ms", or "T# 23h59s999ms".
S7-200 counter symbol names are converted
to S7-1200 counter DB names. S7-200
counter output bit addresses are converted to
a Q bit address, in the counter DB.
