MCP 4 – User's manual
DUEMMEGI
It is also possible to publish non contiguous blocks of virtual points and registers, specifying more
NETWORK
directives, up to a maximum of 8 (as total of V-Words and R-Words). For instance, the following directive
may be enclosed in the same MCP 4:
NETWORK = ( V1 .. V16 )
NETWORK = ( V513 .. V576 )
NETWORK = ( V1025 .. V1056 )
NETWORK = ( R0 .. R8 )
NETWORK = ( R33 .. R37 )
NETWORK = ( R50 .. R52 )
NETWORK = ( R100 .. R100 )
NETWORK = ( R251 .. R255 )
To publish only one register, simply specify the same value for Rstart and Rstop (see
R100
in the previous
example). Each MCP 4 acquires the information published by the other components of the same network
even if it does not contain any
NETWORK
directive; for instance, if only one MCP 4 has to send information to
the other components of the networks, but not vice-versa, then the
NETWORK
directive may be activated only
for the “master” MCP 4 controller.
Remember:
 if a
NETWORK
directive has been inserted in a MCP 4, then also an
ADDRESS
directive must be insrted too
and this last one must be placed before any
NETWORK
directive
 the Words published by a MCP 4 must be different from one to the other in order to avoid
superimposition
 up to 8
NETWORK
directive can be enabled in each MCP 4 in the network

Each MCP 4 acquires the information published by the other components of the same network even if it
does not contain any
NETWORK
directive
 the data exchange mechanism here described also applies between Contatto MCP 4 controllers and
Domino DFCP controller, allowing interactions between the two systems
Example:
Suppose to have installed 2 MCP 4; also suppose to have connected, to each one of them, 1 MOD8I/A, 1
MOD8R, both with address 1, 1 MOANI and 1 MOANU, both with address 2. Suppose that the application
requires to control the outputs of a bus by the input of the other one and vice-versa..
The programs to be written in the two MCP 4 controllers are:
// Program for MCP-4 1
ADDRESS = ( 1 ) // Address of first MCP
NETWORK = ( V1 .. V16 ) // Send 16 virtual points to the other MCP
NETWORK = ( R0 .. R0 ) // Send 1 register to the other MCP
V1 = I1.1 // Copy the local inputs to first 8 virtual points
V2 = I1.2
V3 = I1.3
V4 = I1.4
V5 = I1.5
V6 = I1.6
V7 = I1.7
V8 = I1.8
O1.1 = V17 // Copy the received virtual points to the outputs
O1.2 = V18
O1.3 = V19
O1.4 = V20
O1.5 = V21
O1.6 = V22
O1.7 = V23
O1.8 = V24
R0 = AI2 // Copy the analog input to first register
AO2 = R1 // Copy the second register to analog output
// Program for MCP-4 2
ADDRESS = ( 2 ) // Address of second MCP
NETWORK = ( V17 .. V32 // Send 16 virtual points to the other MCP
NETWORK = ( R1 .. R1 ) // Send 1 register to the other MCP
V17 = I1.1 // Copy the local inputs to the virtual points to be sent
V18 = I1.2
