3.2.5 Data Interchange Table (DIT) 

The Data Interchange Table in the CPU is the  crossroads for data. Any exchange of 
data between functions in the CPU and with the outside world takes place through the 
DIT.  The  DIT  is  an  array  of  16  bit  registers  accessible  from  any  function  or 
communications port in the system for the purpose of interchanging data. 
The  DIT  is  used  to  hold  Configuration  Information  for  the CPU  and Dynamic  Data  to 
be read in real-time. 

3.2.6 Subscription Service 

Central to many applications involving communications across networks is the need to 
replicate  data  between  nodes  on  the  network.  This  feature  provides  an  easy  to  use 
but  powerful  data  replication  service  between  DIT’s  in  the  system,  whether  they  are 
local or remote. This service provides change-of-state detection and error reporting for 
optimum performance and reliability. 

3.2.7 Network Routing Service 

Many  systems  are  constructed  of  multiple  networks  to  overcome  the  difficulties  of 
topology  or  communication  protocol  conversion.  The  Routing  service  provides  a 
means  to  seamlessly  interconnect  these  networks  into  an  integrated  intranet  so  that 
any node in the system may be globally addressed from any other with no regard for 
its physical location. 
The T2 CPU can act as a router in these systems, automatically routing data packets 
seamlessly between nodes on different networks. 

3.2.8 Communications Status Monitoring 

The  Data  Interchange  Table  contains a group of  communication  status registers  that 
may  be  used  for  diagnostic  purposes.  These  registers  monitor  communications 
activity  on  each  port.  The  local  and  global  addresses  for  each  port  may  also  be 
accessed from this group of registers. 

3.2.9 Serial Port Protocol Selection 

The in-built serial port on the T2 CPU comes equipped with three protocol options as 
standard: 
1.  Modbus  Slave  can  be  selected  for  easy  interconnection  of  Maxiflex  I/O  to  third 

party  systems  such  as  Distributed  Control  System’s,  SCADA  software,  or  Master 
Programmable Logic Controllers. 

2.  Conet/s protocol can be selected to interconnect Maxiflex systems over wide areas 

using  the  RS232  port.  This  full  duplex  protocol  provides  full  peer-to-peer 
communications  capability  to  allow  multiple  local  networks  systems  to  be 
interconnected  into  a  single  intranet.  This  efficient  protocol  retains  the  full 
capability  of  the Conet  networking  technology  including  remote programming  and 
the ability to run data subscriptions in both directions simultaneously  

3.  Custom protocol implemented in the FORTH programming language 

3.2.10 Remote Programming 

Every CPU is equipped with a dedicated programming port that is equipped  with the 
Conet/s  protocol.  Using  the  network  routing  function  and  convenient  table 
configuration, it is possible to configure/program every node in a Maxiflex intranet from 
a  single  programming  port.  This  function  significantly  reduces  system  downtime  and 
improves maintenance efficiency and therefore life-cycle costs.
