DUEMMEGI
2- EQUATIONS: TYPES AND SYNTAX
2.1- Equations for the system configuration
2.1.1- Configuration of the modules
Specify the module installed in the system (see MCP IDE Keyword List).
MOD8I/A
= (
I1
)
MOD8I/A
= (
I2
), (
I3
)
MOD8R
= (
O11
)
MOD4-4R
= (
I4
,
O12
)
MOD2DM
= (
I13
,
I14
,
O13
,
O14
)
MOD2DM
= (
I15
,
I16
,
O15
,
O16
)
2.1.2- Power ON status
Specify the status or value assigned to outputs or registers at power up or at reset.
POWERON
= (
O3.1
= 1,
\
O3:1.2
= 1,
\
AO15:1
= 1000,
\
AO16..AO17
= 247, \
R12
= -,
\
C32
= 1245,
\
C33
..
C35
= -,
\
V100
= 1,
\
V1
..
V16
= 1,
\
V17
..
V32
= - )
R12=- means that R12 maintains the value before the power down (RAM has a battery for back-up)
AO16..AO17 = 247
means that outputs AO16 channel 1, channel 2, channel 3, channel 4 and AO17
channel 1 will be set to the value 247 at the power ON. To specify all channels of module 16 and all channels
of module 17, the correct equation is:
AO16:1..AO17:4 = 247
.
2.1.3- Status of fault input modules
The status assumed by MCP 4 for a failed input module; if not specified, MCP 4 assumes the last available
value.
FAIL
= (
I1.1
= 1,
\
I1:3.2
= 0,
\
I5:2.1..I5:2.15
= 1, \
AI15:2
= 2000, \
AI12:1
=
0x1234
)
