A large number of PLC logics and function blocks, user-programmable inputs and outputs and predefined logical event numbers allows the user to create powerful control and automation functions.

Event recorder

The event history saves up-to 10.000 events by using the first-in-first-out (FIFO) principle. Each event provides information such as

• the consecutive number
• the event number
• the event text
• date and time stamp

Events are recorded with a temporal resolution of 1 ms and will be displayed in chronological order. The latest event is on top of the event list.

Fault recorder

The fault recorder saves up-to 1.000 recordings by using the first-in-first-out (FIFO) principle. The fault recorder records:

• all relevant file information (record number, trigger-event number, event text, date and time stamp) 
• all available measuring values of current, voltage and frequency (depending on the SYMAP®Compact+ device variant) for one record

Disturbance recorder

For the “disturbance recorder” function, the device is equipped with a volatile 20 MB RAM-memory to buffer the measuring data. That RAM-memory can be divided in up-to 10 individual memory sections (buffers for recorded  data). One record  can be max. 63,31 s long.

The total number of  protocols that can be run simultaneously depends on the number  of communication interfaces. The protocols under Ethernet interface Modbus TCP, IEC 61850 and  IEC 60870-5 can always work simultaneously.

GOOSE

SYMAP®Compact+ with a number of virtual inputs and outputs allows to extend the use of GOOSE messages for various applications. Most important, it can provide additional safety and flexibility for a wide range of applications.

• 128 virtual inputs
• 128 virtual outputs

High-Speed GOOSE

Under normal conditions, the response time for GOOSE messages incl. application time is approx. 2,7 ms. Under GOOSE performance testing conditions (abnormal conditions), the response time can be up-to 1-1,5 ms longer. However, messages are never lost and there is no further processing.

SYMAP®Compact+

• time span for application and communication approx. 2,7 ms
• time for communication approx. 0,5 ms

The number of binary inputs and outputs can be increased with the Extension Board System (EBS). It consists of several board types with different functions. Each board is designed for DIN rail mounting according to standard DIN TS35. The maximum number of binary inputs and outputs  via extension boards besides the SYMAP®Compact+ basic unit are:

• 50 EBS binary inputs 
• 24 EBS binary outputs 

EB-PS

• power supply 
• 1 system LED
• 3 RJ45 ports and 3 binary inputs with LED status
• 3 BIs (Un: 12/24/48/60/220 V DC; 110 V AC/DC; 230 V AC: parameterizable)  

Housing dimensions (W×H×D): 91,5 x 91,5 x 76,2 mm

EB-BI8-A

• 8 binary inputs with LED status
• 2  independent voltage groups
• BIs (Un: 12/24/48/60/220V DC; 110V AC/DC; 230V AC: parameterizable)

Housing dimensions: (W×H×D): 91,5 x 30,5 x 76,2 mm
 

SYMAP®Compact+ has a compact housing with a small depth. The 90 mm depth including terminal plugs is suitable for almost any compartment, for both shallow and/or narrow compartments. 
For retrofit projects it can save additional mechanical extensions and work when mounting and adjusting the device on the compartment door.

Width: 210 mm
Height: 250 mm  
Depth: 90 mm (incl. terminal plugs)
Weight: approx. 2,5 kg

SYMAP®Compact+ has up-to five microcontrollers for better performance and reliability. One microcontroller for measurement and protection functions (MU), one for control functions (CU), one for the graphic unit (GU), one for communication (ComU) and one for additional inputs and outputs (EBS). In the rare case of a broken touchscreen or damaged graphic unit, the device can still work, or, in case the robust communication card is in failure, protection and control will still work. If control  or protection is in failure, the communication card can remotely send the alarm message that the device is in failure. The intermediate communication between microcontrollers covers different sorts of watchdog functions and self-diagnostic tasks.

Five micro-controllers:

1. Control Unit – CU
2. Measurement and Protection functions – MU
3. Graphic Unit – GU
4. Communication Unit – ComU (optional)
5. Extension Board System (I/O) – EBS (optional)
