Getting Started in Report Generation
Chapter 5
5Ć7
As we have described in this chapter, you can:
Create and execute report generation procedures from the S4B> prompt
Call for procedures to execute from MSG instructions in your ladder
diagram program
The communication that occurs between the RS-232-C device on channel 5
of the 1775-S4B scanner can be in one of two control modes:
Command mode—The data terminal keyboard has direct control over
the operation of the 1775-S4B scanner. When you execute a procedure
at the S4B> prompt, you are in the command mode.
Ladder diagram mode—The ladder diagram program has direct
control over the operation of the 1775-S4B scanner. When a procedure
executes from the MSG instruction to an RS-232-C device connected to
channel 5 on the 1775-S4B scanner, you are in the ladder diagram
mode.
Figure 5.4 shows you the report generation control modes and how to
move from one to another.
