Product Manual Excerpt

The IOP contains 32 range comparators which are analogous to a camshaft with 32 lobes for generating outputs. The position and duration of each range comparator output is programmable. The general operation of range comparators is shown in Figure 1-2.

Range Comparator Block Diagram In the table below, and in the discussion that follows, the 32 range comparators are grouped according to their output function. Range comparators 1–8 control eight %I status bits and eight hardware outputs, range comparators 9–16 control eight %I status bits, and range comparators 17–32 control a 16-bit %AI data word. Range Comparator Operation Summary Range Comparators Modes Update Rate Hardware Output 1–4 Preset Timer 0.5ms always (also output to %I table) 5–8 Preset Timer 0.5ms configurable (also output to %I table) 9–16 Preset 4ms no (output to %I table) 17–32 Preset 4ms no (output to %AI table) 1 1-7 GFK-1028 Chapter 1 Introduction Range Comparators 1–8 Range comparators 1–8 control eight hardware outputs every 500 μ s using one ON preset, one OFF preset and two pulse timers (TIMER1, TIMER2) per output. Range comparator faceplate outputs 1–4 are always available. The four faceplate hardware output terminals used by range comparators 5–8 are shared by input points 9–12. A %Q bit is provided as an output enable for each configured hardware output. Note In order for a hardware output to operate, the associated %Q Output Enable bit must be ON. The status of each range comparator output is reported to the PLC using a %I bit. If a hardware output is not configured for a range comparator, the %I status bit is still updated. This feature allows PLC logic to perform bit operations using range comparator 5–8 status even if the associated hardware output terminal is used as an input point. Range comparators 1–8 can be configured to operate in one of two modes: PRESET or TIMER . In PRESET mode, the range comparator output operates as follows: Preset Values Range Comparator Output OFF > ON ON when ON PRESET v ENCODER DATA v OFF PRESET (ON condition includes Preset points) OFF < ON OFF when OFF PRESET v ENCODER DATA v ON PRESET (OFF condition includes Preset points) OFF = ON ON when ENCODER DATA = ON and OFF PRESETS Example: If Outputs 1 and 2 have been configured for PRESET MODE, Output 1 will be ON for counts 80 through 106, and Output 2 will be OFF for counts 80 through 106. OFF PRESET =80 ON PRESET = 80 OUTPUT 2 OUTPUT 1 a45368 ON PRESET =106 OFF PRESET =106 1 1-8 GFK-1028 Series 90-30 I/O Processor User’s Manual - June 1994 In TIMER mode, the comparator output turns ON when the ON PRESET is reached. The output stays ON until TIMER1 has elapsed. The output turns ON again when the OFF PRESET is reached. The output stays ON until TIMER2 has elapsed. By programming TIMER1 or TIMER2 to zero, only one output pulse per revolution will be produced.
