B 5231 / H51q-MS (0605)
99
– Dual Port RAM for fast memory access to the second central module (not used in the
H51q-MS system)
– Hardware clock, battery buffered
– I/O bus logic and connection to the input/output modules
– Watchdog
– Power supply monitoring, testable (5 V system voltage)
– Battery monitoring
2.2 Coprocessor module F 8621A
Right of the central module of the H51q-MS PES up to three coprocessor modules can be in-
stalled. The coprocessor module mainly contains:
– Microprocessor HD 64180 with a clock frequency of 10 MHz
– Operating system EPROM
– RAM for a PLC master project
– Two interfaces RS 485, via communication software function block setting of the baud rate
up to 57600 bps
– Dual port RAM (DPR) for the communication with the central module via CPU bus
2.3 Communication modules F 8627/F 8628, F 8627X/F 8628X
Right of the central module of the H51q-MS PES up to five communication modules can be
installed. The communication module mainly contains:
– 32-bit RISC microprocessor
– Operating system
– RAM for further protocols
– F 8627 Ethernet interface (safeethernet, OPC, ...)
F 8628 Profibus-DP slave interface
– Dual port RAM (DPR) for the communication with the central module via CPU bus
Special applications with the communication module F 8627X:
– connection of the central module to a PADT (ELOP II TCP)
– connection to other communication partners within an Ethernet network (Modbus TCP)
Special application with the communication module F 8628X:
– ELOP II TCP connection (PADT) via the Ethernet interface of the F 8628X to the H41q/
H51q controller
3 Startup and maintenance
A battery change of the buffer batteries on the power supply monitoring module and the central
module (CPU in operation) is recommended every 6 years.
Buffer battery with soldering lug: HIMA part no. 44 0000016.
Buffer battery without soldering lug: HIMA part no. 44 0000019.
Further informations see also catalog H41q/H51q, chapter 9, "Startup and maintenance".
Note The RAM for the master project is buffered via the batteries on the
power supply monitoring module F 7131.
