Flags (M)
These are intended for the interim storage of states for the purpose of later
processing. The flags are set to 0 during the initialisation of the program.
Hold flags (K)
Are used in the PN program of the PROTECT-PSC for non-volatile storage of
states with an installed back-up-battery. This function does not exist in the PS pro-
grams of PROTECT-PSC. They can be set analogously to the flags. The hold flags
are set to 0 when initialising the program.
Special flags (V)
Provide additional information on the state of the PROTECT-PSC (see Chapter
6.10.8).
Timers (T)
Connect a timer module to an address.
Communication (L)
Are not used in the PROTECT-PSC .
Edge detection (P)
Connect an edge detection module (high or low) to an address.
Gateway (EL)
To communicate with an optionally connectable gateway, part of the data memory
of the gateway is faded in to the address area EL000 to ELBFF. The address area
EL000 to EL3FF is reserved for the PS program. The address area EL400 to
ELBFF is reserved for the PN program. See Chapter 6.10.8 for a detailed descrip-
tion.
PS/PN
communication (EM)
The address area EM000 to EM7FF is available for communication between the
PS and the PN program. EM000 to EM3FF is reserved for the PS program and
EM400 to EM7FF is reserved for the PN program. See Chapter 6.10.8 for a de-
tailed description.
Data registers (D)
User memories for data and working register for the logic functions (AND, OR,
NOT, XOR).
Value registers (N)
Contain the current counting value of a timer. A value register with the same
address is allocated to every timer register. Timer statuses can therefore be read
out or modified with suitable commands.
Special registers (S)
Contain data such as error messages, time/date, program version etc. (see Chap-
ter 6.10.8). Chapter 7.3.2 / 7-3 contains a description of the error messages
(memory area S200 to S24F).
