Report Generation
Chapter 23
23-13
Important: Automatic report generation can also be activated
automatically upon initialization of the industrial terminal if you move
parity switches 4 and 5 to the up position on the industrial terminal’s main
logic board (Figure 23.2). To find these switches, turn power off and
remove the keyboard.

Once automatic report generation is activated, the message request bits are
scanned by the industrial terminal for a false-to-true transition. Each time
one of the request bits goes true, the corresponding message is printed
automatically.
You can terminate automatic report generation by pressing [Esc]. The
display returns to the ladder diagram if automatic report generation was
entered by a command from a peripheral device.

Bits 10-15 of word 027 are used to control messages 1-6 (Figure 23.3). Bit
027/10 is the request message number 1, bit 027/11 is the request bit for
message number 2 and so on. The remaining 64 messages have a
user-defined file of message request bits for control. Bit 027/16, the busy
bit is set when any of messages 1-6 are requested and remains set until all
requested messages have been printed. Once all messages are printed, bit
027/17 stays on for 300 milliseconds and then resets.
