Generic Instrument Setups

The generic instrument’s data will be stored in certain registers on the host instrument, such as the 9130 controller.  Each instrument is allotted a certain set of registers, starting with register 1000.  To determine the beginning register, use the following calculation: (100 * generic instrument’s number (1 – 16)) + 900.  Therefore, instrument 1 would begin at register 1000: (100 * 1) + 900. Instrument 7 would begin at register 1600: (100 * 7) + 900.  Each instrument is allotted 100 registers, therefore, instrument 1’s allotment is from register 1000 to 1099 on the 9130 controller, instrument 2’s allotment is from register 1100 to 1199 on the 9130 controller, etc.

The Generic Instrument Setups menu is split into three parts: Configure Generic Instruments, Configure IP Addresses, and Configure Block Writes.

 

Configure Generic Instruments

This screen is where the user can configure the main sections for each generic instrument.  The drop-down box in the top left will select the generic instrument to set up.  The options are: Instrument 1 – Instrument 16.

The three reads can be set up in the grid in the top of the form.

 

The Instrument Register field will be the register in the 9220 controller.  The range is 0 – 32767.  The Count field will be the number of successive registers to read.  The range is 0 – 100.  The Storage Offset field will be the offset in the generic instruments registers (1000 – 1099 for Instrument 1, 1100 to 1199 for Instrument 2, etc).  The range is 0 – 99.

 

The setup for the PV (Process Variable), SP (Setpoint), and Out (Output) can be done in the grid in the bottom of the form.  The Offset field is the instrument’s offset.  The range is 0 – 32767.  The Instrument Register field is the register in the 9220 controller.  The range is 0 – 32767.  The Input Type field will determine what kind of type the value will be.  The options are: Integer, Big Endian, Big Endian Byte Swap, Little Endian, or Little Endian Byte Swap. 

The Exponent field will determine if there is an exponent value.  Checking the checkbox will indicate that there is an exponent.  The Input Scalar field will determine the input scalar range.  The range is -128 – 127.  The Output Type will determine what kind of the output value will be.  The options are: Integer, Big Endian, Big Endian Byte Swap, Little Endian, or Little Endian Byte Swap.  The Exponent field will determine if there is an exponent value.  Checking the checkbox will indicate that there is an exponent.  The Output Scalar field will determine the Output scalar range.  The range is -128 – 127.

 

Click on the Done button to close down the screen and save the changes, or select a new instrument to configure another instrument.

 

Configure IP Addresses

 

 

This screen will allow the user to set up the IP addresses for each of the generic instruments, as well as assign a port number for the instrument.  The first four columns in the grid are for the IP address.  The IP address follows the standard format, i.e., 192.168.1.230.  To use this IP for instrument 5, 192 would be entered in the first column, 168 would be entered for the second column, 1 would be entered for the third column, and 230 would be entered in the fourth column.  The port number would be entered in the fifth column, which also has the “Port” heading.  The IP address columns have a range of 0 – 255, and the Port column has a range of 0 – 32767.

 

Configure Block Writes

This screen will allow the user to configure up to five (5) block writes for the instruments. 

 

The Instrument field is the instrument to use the write for.  The range is 0 – 32.  The Update Interval field is the update time, in seconds, to perform the write.  The range is 0 – 300 seconds.  The Source Register field is the 9220 register where the values will come from.  The range is 0 – 32767.  The Count field is the number of successive registers to read.  The range is 0 – 80.  The Target Register field is the 9220 register to put the count into.  The range is 0 – 32767.
