5.4 Menus 70-75 - PLC Registers
These menus provide access to the PLC registers. The PLC registers are Signed 32-bit
integers available for user programs and CTNet communications.
The PLC registers are split into 6 sets of 100 parameters numbered 00 to 99. The
registers can also be accessed from within a user DPL program by a special variable
name or array name.
You will see from the above table that each parameter within menus 70 to 75 has and
equivalent DPL variable. This means that you can use either format for accessing a
parameter within these menus.
e.g. Pr 72.01=1 will do the same as _R01%=1, Pr 75.65=66 will do the same as
_U65%=66 etc.
Menus 70, 71, 74 and 75 can all be saved into the non-volatile flash memory upon
request or automatically when the drive goes into under-voltage (refer to section
5.2 Saving Parameters on page 28 for more information).
Menus 72 and 73 are used for CTNet cyclic data transfer but if this feature is not being
used the registers may be used for any other purpose. However this should be avoided
if possible in case cyclic data is used in the future.
Parameters #72.79 and #73.79 will be reserved if AUTOSYNC is in use.
Parameters #71.80 thru #71.99 may be used for the RAM File Recording
