Control Module Errors

 The control module performs status checks on the DSO module. An error will appear in the report function of an operator interface. Refer to the Product Instruction for the operator interface being used (Table 1-2) for an explanation of these reports. Function Code (FC) 83 output block N in the control module configuration is the DSO status flag (logic 0=good; logic 1=bad). You can use an operator interface to monitor this block. If the status flag is a logic 1, check the front panel module status LEDs and the operator interface report function to determine corrective actions. NOTE: If FC 83 specification S3 is set to 0, the control module will trip when the DSO module fails. Changing specification S3 to a 1 allows the control module to continue to operate if any DSO error condition exists.

The address set on address switch S1

 and in the control module configuration must be the same. The control module generates a MISSING SLAVE MODULE if they do not match. Verify that the address set on switch S1 is the same as the address in FC 83 specification S1. If not: 1. Remove the module and change the setting of address switch S1 to correspond with the control module configuration (refer to INSTALLATION in Section 3 for the procedures to set an address and to install a digital output module). OR 2. Modify the address in the control module configuration (FC 83 specification S1) to correspond with the address set on address switch S1 of the digital output module. Use an INFI 90 OPEN operator interface to modify the configuration. For procedures on how to modify a function code specification, refer to the applicable instruction manual for the operator interface being used.
