Four types of counter instructions are available with the PLC-2/30 Controller: Counter Instructions Up-Controller (CTU) Counter Reset (CTR) Page 108 Chapter 5 Bit 14 is the overflow/underflow bit. It is set to one when the AC value of the CTU exceeds 999 or the AC value of the CTD goes below 000.

Usually this is set to 0, however it can be set to other values to increase, or reduce the time to reach the Preset value. Because the Preset and Accumulator bits are addressable, the values can be changed within the program (based on other rung instructions). Programming Problem.

Ladder logic can examine a bit controlled by OTL as often as necessary. When you assign an address to the OTL instruction that corresponds to the address of a physical output, the output device wired to the screw terminal is energized when the bit is set.

Simply tell PLC Reports how the reporting should take place by using the clear text instruction set. The instruction set is an English-language plaintext. For example, to log the online value of variable 2 into the archive “Supply Air Temperature”, simply use the statement “Archive Variable (2, Supply Air Temperature)”. In the first line of the program, LD is the operator, A the operand, and the words at the ends of program lines and in parentheses shown and preceded and followed by * are comments added to explain what the operation is and are not part of the program operation instructions to the PLC. LD A is thus the instruction to load A into the memory ...

From the PLC-5 Instruction Set: USING SBR The optional SBR instruction is the header instruction that stores incoming parameters. Use SBR only if you want to pass parameters. When you pass parameters, the SBR instruction must be the first instruction in the first rung of the subroutine. This rung must also have an output instruction.
