SCADAPack Wonderware driver

A

Thread Starter

anonymous

I am looking for a modbus communication driver between a PC running Wonderware Intouch and the Control Microsystem product SCADAPack. The SCADAPack uses IEEE convention in their floating point numbers. The standard Wonderware modbus driver does not follow this convetnion and swaps the registers. The driver I am looking for will swap the registers, so that register manipulation in the SCADAPack is not necessary.
Thanks for help!!

If you already have FactorySuite then use InControl. The OpenModbus driver allows swapping of nibbles, bytes and/or words in any combination. You can also reverse the bit order, scale and mask out bits (for use with analog modules). You can move tags easily from InControl to InTouch. The driver supports ASCII, RTU or TCP/IP. If needed, you can also use InControl for any 'scripting' or pre-processing
of data before sending to InTouch, using your choice of IEC languages.

Try not using the r:, or i: prefix for the modbus address - you may be suprised to find that the bit order swapping is not required. this using the Modbus IO Driver.
