Electroplating Control Software

Modern Machine Shop, Oct, 2000 by Elizabeth M. McPhail

Updating its DOS-based software, the company introduces DynaComm II, a 32-bit, Windows-based software that operates under any of the current platforms available (95/98/NT/CE). Employing either the simple point-and-click or touch-screen technology common for Windows applications, DynaComm II provides an electroplating process control program for the PRO-Series and DC rectifiers.

This program consists of an Operator Interface (OI) for parameter entry and display and a Control Server (CS) to control and monitor the rectifiers. These two applications use a Windows socket connection to interchange data using the Internet protocol. This two-part design allows DynaComm II to be installed on a single computer for a stand alone application or to be installed on separate computers where the operator's and rectifier's positions can be separated by feet or miles.

This dual application design also permits any application program that will support the Internet protocol to be connected to the Control Server. The company can create custom additions to the Operator Interface to control and monitor other plating line functions, such as temperature, pH, and so on, whether servers exist or need to be written.

DynaComm II allows multiple monitoring and controlling options. More than one Operator Interface can be connected to a CS for multiple monitoring/control locations for a single line. Or, multiple Control Servers can be connected to a single OI for monitoring of multiple stations from a single supervisory office workstation.

Data logging is an optional feature, and when enabled, this function automatically stores data accumulated during the plating operation. This data can be downloaded to an electronic spreadsheet for further analysis, providing users with a written record to verify rectifier performance for all parts and batch runs against specifications and tolerances required.

To prevent loss or corruption of data, DynaComm II also features UPS power monitoring and control. If AC power is interrupted, it senses the line loss or brownout, closes the open files, closes itself, shuts down Windows and disables the UPS output. The minimum system requirements include a 233 MHz Pentium PC, 32 MB RAM, 4 MB Video RAM, 6 MB free hard drive space, two RS232 serial ports and a 10/100 Base T Ethernet port. Additional hard drive space will be required for plating recipes and data logging storage.
