The programmable Sigma S664 controller is a multifunctional device for measuring different types of signals. It has built-in six analog inputs, six digital inputs and four relay outputs. It also supports a communication bus for a wide range of peripheral extensions - analogue and digital, inputs and outputs.
The controller is designed for stand-alone operation and in-system operation. Performs measurement and analog signal processing, digital input, digital output, inputting parameter values measured by field devices and HART-modem transmitters, communication with external devices on different data exchange protocols.
Extremely flexible programmable communicator. It can collect data via the built-in RS232 port on up to 12 devices and send their data compressed and encrypted to the SCADA system using the GPRS connection in the most power efficient mode.
The EM203A HART CONVERTER device is a HART protocol converter to MODBUS TCP or MODBUS RTU over TCP, through which the readings of an arbitrary HART device (transmitter, flowmeter, etc.) can be monitored via PLC or PC directly via an Ethernet network or over the Internet. Only one HART device, could be read at a time, with polling address 0 and its current signal can also be used. Data extraction period from the HART device is 2 sec.
The EM203A HART CONVERTER device is a HART protocol converter to MODBUS TCP or MODBUS RTU over TCP, through which the readings of an arbitrary HART device (transmitter, flowmeter, etc.) can be monitored via PLC or PC directly via an Ethernet network or over the Internet. The converter can be connected to eight HART devices in "multidrop" mode, with their polling address being between 1 and 15. If the HART device is only one, its number can be 0 to 15. Data retrieval period is equal to the number of devices multiplied by 1.5 seconds.
The module is designed to connect up to six devices equipped with a serial communication channel RS232 or RS485 to local Ethernet networks. Its compact size and its diverse capabilities make it convenient to provide access to devices at a great distance over the Internet, as well as from any point on a connected local area network.
The module is designed to connect six devices equipped with serial RS232 or RS485 communication channel to a common RS232 or RS485 communication channel, enabling multiple devices to connect to a modem or interface converter.
The WPS32 (Windows Process Control Station) program package is developed to design and implementation of the operator interface of distributed microprocessor systems for management of technological processes, based on the Modbus compatible controllers, Sigma series controllers and some others for which link drivers have been developed.
