• Analog Output Signals
Figure 2-29 shows typical analog output channels and where you can test the signals.
Analog output signals in a specific plant are shown in the connection diagrams for the
plant.
Proceed as follows to check analog channels:
– Use the blocking command (BL) to block any PC programs already entered.
– Ensure that the data base connections for the output signals concerned are correct.
– Use the command MDB on the engineering unit to present the element in the data
base, set the VALUE and check that the corresponding output shows this value.
Then measure the value on the screw terminal block of the corresponding connection
unit end and, if practical, at the process as well.
– When you are checking analog output signals, use a multimeter to test that an output
signal is obtained over the complete signal range.
For a description of adjustment of analog output signals, see Chapter 5, Maintenance.
Readjustment of Analog Output Signals
AO boards are factory adjusted for voltage output signals. If current signal is
desired/jumpered, you must readjust for maximum accuracy. Please follow the instructions
given in Section 5.5.12, Channel Adjustment on AO Board.
2.5.3.10 Listing of PC Program and Data Base
When the PC program is entered, you can obtain a printout from the printer connected to the
engineering tool for editing or documentation purposes. Two different types of printout are
available:
• Printout as a graphic diagram with LPCD (List PC Diagram). See Figure 2-30.
• Printout as a program list with LPCL (List PC List). Use this to your advantage when you
need rapid listing of a PC program on a printer or screen and when listing on a printer
without graphic mode. See Figure 2-31.
Use the command LDBD (List Data Base Diagram) to print the data base.
All procedures are described in the manual AMPL Configuration Advant Controller 400 Series.
