7-1 Application Examples
H Reading Present Value Output Signals with an OMRON PC
D System Configuration
• Cam Positioner: 3F88L-160 (16-point type)
• Present angle value output setting (Function No. H, Parameter No. 4): “1” (4-digit present angle, no
units)
• CIO bits: a, b, c, d, e
• Data memory used to store present value data: D01000 (work), D01001 (present value data storage)
• Wire cam outputs 1 to 16 to IN0 to IN15 on the Input Unit allocated to word 0 in the PC.
CAM16 Bit 15, word 0
CAM15 Bit 14, word 0
CAM14 Bit 13, word 0
CAM13 Bit 12, word 0
CAM12 (1-digit LE signal) Bit 11, word 0
CAM11 (2-digit LE signal) Bit 10, word 0
CAM10 (3-digit LE signal) Bit 9, word 0
CAM9 (4-digit LE signal) Bit 8, word 0
CAM8 (Cam No. 8 output signal) Bit 7, word 0

D Points to Consider
The 3F88L-160/162 Cam Positioner present value outputs have been adjusted to suit the M7E Display
Unit. The displayed data is, therefore, the reverse of the normal signal.

Note 1. On this table, “0” indicates OFF and “1” indicates ON.
Note 2. The data on this table is for 3F88L-160 Cam Positioners. For 3F88L-162 Cam Positioners,
CAM16 to 13 will be CAM32 to 29. (Refer to 3-6-10 Present Value Output Function.)
Note 3. In PRGM/SET mode, a code that gives “A” will be output when the bit is reversed (all digits).
The following cases, however, are exceptions to this rule.
During trial operation or teaching: The display data will be output according to the present value
output settings.
During origin compensation: Display data is output with the origin compensation absolute angle
flashing.
(For approximately one second, “the code (all digits) that will give “E” when origin compensation
absolute angle changed to bit reversal” will be repeatedly output.
