Modbus RS-485 or Modbus Plus communication with local serial line devices
-
Dual Modbus TCP Ethernet communication between LCU (Local Control Unit) and SCADA
Modicon Mx80 with RTU Module
This architecture has the following features:
-
Power supply, DI and DO range from 24...125 Vdc (the modules from Apollo project have supported the voltage range from 88 to 150 Vdc)
-
Time stamping module with 1 ms resolution
-
IEC 611131-2 zone C and IEC 61000-6-5 certification
-
Modbus RS-485 or Modbus communication with local serial line devices
-
RTU protocol supported with DNP 3.0, IEC 60870-5-101, IEC 60870-5-104, and Modbus TCP
External Time Synchronization
In this sample configuration, the synchronized time is provided by an external GPS source:
1
engineering station
2
operation station
3
maintenance station
4
blue network router
5
red network router
6
primary rack configuration
7
secondary rack configuration
8
remote I/O drop
9
third-party time server
10
GPS transmitter
11
satellite
In this sample configuration, the synchronized time for the M580 PAC system is provided by an NTP server:
1
engineering station
2
operations station
3
maintenance station
4
NTP server
5
network router
6
primary rack configuration
7
secondary rack configuration
8
remote I/O drop
Typical Configuration with BMXERT1604.2 Module
Standalone M580 CPU + local main rack + extended main rack + remote rack
A
main local rack
B
extended local rack
C
remote rack
|
Maximum Time Difference
|
Value
|
|
two modules on the same rack (including an extended rack)
|
1 ms
|
|
two modules between the local and remote rack (with a BMECRA31210 module)
|
12 ms
|
|
two modules between remote racks (with BMECRA31210 modules)
|
7 ms
|
NOTE: The physical distance of the remote rack and the number of BMECRA31210 modules installed do not increase the difference of time stamping values between the local and the remote rack.
