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
