The following symbolic names may be used on deployment together with a
VIPA PLC by selecting "S73&400" server:
Symbol Memory type Modificator Address
DBx Data block with No. x B, C, W, S, D, L, F Byte offset
M Internal memory (flag) B, C, W, S, D, L, F Byte offset
C Counter W, S Counter No.
T Timer W, S Timer No.
I Process inputs B, C, W, S, D, L, F Byte offset
Q Process outputs B, C, W, S, D, L, F Byte offset
PI Peripheral inputs B, C, W, S, D, L, F Byte offset
PQ Peripheral outputs B, C, W, S, D, L, F Byte offset
Modificator Type Range of values
B Byte 0 ... 255
C Byte with sign -128 ... 127
W Word 0 ... 65535 (default)
S Word with sign -32768 ... 32767
D DWord 0 ... 4294967296
L DWord with sign -2147483648 ... 2147483647
F Float +/- 3.4E38
With each memory type there is the possibility to access a bit. Here add a #
and the bit no. to the
Address
name.
For the bit no. the values 0 ... 7 may be used.

Modificator
automatically the type "Word" is used. With
data blocks a
Modificator
is always to be entered.
Address Description
MW4 Flag word 4
