Configure Series 2000

Notes on Resolution

Data values limited to 16 bits per parameter.

This reduces the active range of parameter values to 65536 counts. Series 2000 implements this as -32767 (8001h) to +32767 (7FFFh).

In integer resolution all parameters are rounded to the nearest integer value.In full resolution mode the decimal point position is implied.

100.01 would be transmitted as 10001

From this, and the 16 bit resolution limitation, the maximum value communicable with 2 decimal place resolution is 327.67.

The parameter resolution will be taken from the slave user interface, and the conversion factor must be known to both master and slave.

Wonderware Modbus DDE Server

Microsoft® Windows™ Application Acts as a DDE (Dynamic Data Exchange) Server

Primarily intended for use with Wonderware's InTouch (version 3.01 or later)May be used by any Microsoft Windows program capable of acting as a DDE client.

Communicates with external devices via a serial connection. Using modems or multi-drop transceivers server can support up to 247 devices on each serial ports.

8 of 61mrd/2ks_ww


DDE Address Convention

Application NameThe name of the Windows program (Server) that will be accessing the data element. In the case of data coming from or going to Modbus compatible equipment from this Server, the application portion of the DDE address is -- Modbus.

Topic NameMeaningful name(s) are configured in the DDE Server to identify specific devices. These names are then used as the topic name in all DDE conversations to that device. For example -- c2FastInstr1.

Item NameA specific data element within the data topic. In the case of Eurotherm controllers, the item name represents a parameter such as measured value (1) or setpoint (2). Each parameter in a Eurotherm controller has a unique Modbus address. For example -- 40002 S.

9 of 61mrd/2ks_ww


The DDE Server supports item/point names that are consistent with the point naming convention used by Modicon PLCs. The server allows you to select a Slave Type when you configure the topic definition for the PLC.

The PLC Address Ranges supported are:

Still Doesn’t Work?

Check the Wonderware Logger, it provides useful messages Check the cabling -- again.

If Baud Rate is 19K2, make sure UART’s are 16550. If not, decrease Baud Rate to 9600 or slower.

Check that the Baud Rate, Data Bits, Parity and Stop Bits are matched -- again. Computer locking up? Make sure there are no INT conflicts with other serial ports or other cards in the PC.

Plugged into the correct COM port? COM port mislabled? COM port enabled?
