Chapter 4 Installing and Using the FieldPoint SoftwareFP-1000/1001 User Manual 4-20 ni.comSome OPC clients that do not support this “GetErrorString” methodmight still provide a way for you to manually look up the FieldPointmessage corresponding to the error code using the method.Using FieldPoint with an Optomux ServerThe FP-1000/1001 supports many of the commands of the standardOptomux protocol, so it is possible to communicate with the FieldPointhardware using an Optomux server. This might be appropriate for anapplication where you are integrating FieldPoint into a system that isalready using an Optomux server, or if you are using FieldPoint with anoperating system not compatible with the other software options providedwith your FieldPoint software. (The FieldPoint software does not include ageneric Optomux server.) The FP-1000/1001 Programmer ReferenceManual has detailed information on the protocol used by theFP-1000/1001, including which standard Optomux commands aresupported and which are not. It is also a reference for working with theASCII protocol directly. However, a general overview of using FieldPointwith Optomux servers is provided here as a guide.• Standard Optomux commands do not allow for the configuration ofhardware settings, so you must use FieldPoint Explorer to set yourhardware settings (such as are set in Step 7 in the Getting Started withFieldPoint Explorer section, earlier in this chapter). If you make thesesettings the default power-up settings for the hardware (as described inStep 10 of that section), the FP-1000/1001 network module alwayspowers up the I/O modules to these settings, so you do not need to runthe FieldPoint Explorer more than once to configure your networkmodule.• The Optomux address of the FP-1000/1001 network module is thenetwork address set by the switches as described in Table 2-1, NetworkAddress Switch Settings for the FP-1000/1001, in Chapter 2,Hardware Installation and Configuration. The Optomux address ofthe I/O module in the first terminal base attached to the networkmodule is one plus the address of the network module, and so on. Inmost cases you do not need to communicate with the network module,expect perhaps to change watchdog timer settings.• Optomux analog data contains only 12 bits of resolution and is usuallyrepresented as an integer from 0 to 4095. Data that is returned from aFieldPoint analog channel has its minimum value represented by 0 andits maximum value represented by 4095. In some cases Optomux data
