Watlow 12LS Controller - Manual (Page 100)

7-2
If the address is not changed the unit will probably have the default address 1. If the address
must be changed on line, ANASOFT will indicate communication errors as it will probably get
responses from two controllers at once. The address should be set as quickly as possible, and the
current job reloaded to ensure the correct parameters are at each controller.
7.2.1 Computer Problems
The computer can be checked by running standard programs that use the display and the printer.
The serial interface must be functioning. This is harder to test since most programs do not utilize
the serial interface. Check any computer problems with the computer supplier.
7.2.2 Computer Software
This can be divided into: ANASOFT and user written software:
7.2.3 User Written Software
For user written software a simple routine that sends and receives a command from the 12LS
should be written and tested initially. The ideal routine sends and receives commands displaying
both sets on the computer monitor. Since the protocol includes all characters, the display should
show the hex numbers of the characters sent in both directions.
Once successful communications is established, this program can be used as a check if problems
arise in the operating software.
7.2.4 ANASOFT
ANASOFT is a complete menu driven software program which includes error detection and
diagnostic messages. If ANASOFT will not run at all please see the ANASOFT manual for
detailed information. The following can be checked:
1. Correct path for files run the install program and check the disk drive and path for the
data files.
2. All files present - check that all necessary files are present and on the specified directory.
3 Sufficient memory free ANASOFT requires 512K memory free to run. You can use the
DOS command CHKDSK to view the free memory. If there is insufficient memory check
step 4.
4. Delete any memory resident programs check the AUTOEXEC.BAT to insure no
memory resident programs are automatically run on start-up. Some memory resident
programs may interfere with ANASOFT.
