GPRS
Use GPRS wireless data transmission services to access your Vision PLC via the Internet. Vision can transmit IP packets of data to a remote PC connected to the Internet via GPRS modem, using a dedicated IP.
GPRS enables you to operate remote PLCs on-line, upload, download, debug programs, and log application data—no wires required.
GSM/SMS
Use your cellular phone to implement real-time remote control in your application. Vision PLCs can send and receive SMS messages to/from any GPRS/GSM/CDMA cellular phone. The SMS-enabled controllers can:
- Send & receive text and variable SMS messages
- Route different messages to different phone numbers
- Auto-acknowledge received messages
- Answer data requests—from your cell phone, directly back to your cell phone
Remote Access
Use your PC to access remote PLCs via network connections, cellular, or landline modems. Unitronics’ unique Remote Access utilities enable you (via Ladder software or independently) to remotely:
- Operate the controller’s HMI panel via PC
- Run, reset, or initialize a controller
- Download, upload, or debug PLC programs
- Read, write, and store online operand and system values
MODBUS
Use serial MODBUS to create a multi-device network, and establish master-slave communication between Unitronics PLCs and any connected device that supports the MODBUS protocol (SCADA systems, servos and other peripheral devices). Any Unitronics controller in the network may function as either master or slave.
CANbus
CANbus enables inter-PLC data exchange, for implementation of efficient distributed control. Use Unitronics’ CANbus protocol to integrate up to 63 PLCs into one high-speed network. CANopen is also supported
OPC/DDE Server
Unitronics’ OPC/DDE servers enable the PLC to exchange data with external applications. Use it to interface with SCADA systems, or to read/write PLC data from/to Excel, Access, or other Windows-based applications.
OPC/DDE Server software utilities are free downloads.
OPC/DDE Server software utilities are free downloads.
Additional Communication Protocols
The “Protocols” function block enables the Vision PLC to communicate, via RS232 and RS485, with a broad variety of external devices, such as bar-code readers and servos.
DataXport (to Excel)
This powerful software utility captures PLC application data and exports it to Excel files for logging or processing. Data is exported either directly, via network connection, or via modem in accordance with a pre-set schedule—or instantly exported in response to a user request.
DataXport is a free download
