Use of Do I/O and Suspend I/O
The Do I/O and Suspend I/O program functions can interfere with the output autotest. They
should not be used in any GMR application program.
Programming Restrictions for TÜV Applications
Some of the program instructions listed above can not be used for a GMR system that
will be applied in an Emergency Shut Down (ESD) application for which for a TÜV site
application approval will be sought. See Appendix A for details.
Estimating Memory Usage
The GMR system software version 2.06 uses approximately 318,688 bytes of the CPU’s
memory. To determine how much of the 512 Kbyte memory (IC697MEM735) used on
the CPU788 and CPU789 remains for the ladder logic application program, use this
equation:
Max. User Ladder Logic Application Program Size = 524,288 bytes – 318,688 bytes – User Reference Tables
The size of the User Reference Tables depends on your configuration and actual
application program. See the LM90–70 Programming Software User’s Manual (GFK–0263)
for more information.
Estimating Bus Scan Time
If you want to estimate the bus scan time, see page 4-6 for instructions.
