SCADA communication card REG-PED
Working as a coupling-device with control centres or with central units, the REG-PED operates with all telecontrol protocols.
- boots itself after power-on
- coordinates the telegram traffic between one or more substation units and WT- and/or modemconnections to central stations or substations
- checks automatically and continuously the memory of the device
- controls the watchdog
- parameters can be set online at any time
- adjustable to any telecontrol protocol
- multiple choices for connection such as fibre optics, RS 485, RS 232
The REG-PED board is equipped with an 32 Bit PowerQuicc - processor PPC885 and represents an independant computer, with an address-range of 1 GByte.
The CPU runs at a speed of 133 MHZ. The board has a maximum capacity of 2 RAM modules with 128 MB in total memory as working memory.
Depending on the kind of the module the storage capacity for saving of special system device data as well as for the specific remote control protocol structure are up to 64 MB flash memory.
All 16 hardware-timers are required for the realtime operating system used. One timer is used for the system cycle. All of the prozessor-included UART- modules turn the 5 asynchronous V.24-interfaces. 3 of these interfaces have their own baudrate timers.
The PARAM interface is able to work from 1200 up to 115200 baud and the other serial interfaces 1-4 from 300 Bd. up to 115200 baud. For serial coupling in pulse-width-modulation (pulse-duration-m.) 100 Bd. up to bis 2400 Bd. are available.
All interfaces can be used either in PWM- or in PCM (pulse-code-m.)-mode or as control lines for modem serving up to 4 coupling partners can be served.
Despite the functions running by different software branches on REG-PED, there are general functions in order to protect the REG-PED module against malfunctions. These functions are implemented by hardware supplements and by software parts.
