Communication with systems by the TEDIA company (Czechia)
The
TEDIA company (
http://www.tedia.cz, Czechia) is manufacturing the measuring devices, cards and
MicroUnit modules for distributed systems. A list of the communication options between these devices and the PROMOTIC application is following.
Communication with MicroUnit modules
The
MicroUnit modules kit can be used especially for distributed systems design for monitoring or controlling of technological processes. Each module acts as remote intelligent unit procesing analog/digital signals and communicating with superior computer via serial link of
RS485 standard.
Communication by the Modbus protocol:
New types of
MicroUnit modules support the
Modbus RTU protocol (since
2011).
For this communication in the PROMOTIC system can be used:
Communication with DAQ cards
For the data transfer from
DAQ cards into the PROMOTIC application drivers by the
TEDIA company can be used:
For ISA DAQ cards the TED_DAQ driver.
For PCI DAQ cards the TED_DAQ01 driver.
The above mentioned drivers are in fact DLL libraries that can be accessed in the PROMOTIC system using the
PmaDll object.
