Page 22 They can be used in the control program for error detection. The module continues to convert analog data to the minimum full range value while this bit is set (1). The bit is reset (0) when the error clears. Publication 1763-RM001D-EN-P - September 2011...
Page 23 (15), and bit 14. If bit 15 equals 1, the module sets the output value to 0V or 0 mA. If bit 15 equals zero and bit 14 equals 1, the module sets the output value to 10.5V dc or 21 mA. Publication 1763-RM001D-EN-P - September 2011...

Page 28 Similarly, the faster the filter setting, the less immune the analog inputs are to electrical noise. The less immune the analog inputs are to electrical noise, the faster the inputs will be to update. Publication 1763-RM001D-EN-P - September 2011...
Page 29 The analog input circuits are able to monitor voltage signals and convert them to digital data. There are three terminals assigned to the input channels that provide two voltage inputs, and a return signal (commons). Publication 1763-RM001D-EN-P - September 2011...

Page 89 Chapter Using the High-Speed Counter and Programmable Limit Switch All MicroLogix 1100, except the 1763-L16AWA, have one 20 kHz (40 High-Speed Counter ) high-speed counter. The counter has four dedicated inputs that Overview are isolated from other inputs on the controller. HSC0 utilizes inputs 0 through 3.
Page 90 The HSC function, along with the PTO and PWM instructions, are different than most other controller instructions. Their operation is performed by custom circuitry that runs in parallel with the main system processor. This is necessary because of the high performance requirements of these functions.

Page 571 Controller MicroLogix 1100 Series A firmware didn’t support values above 20000 (20kHz). However, these values are changed to unsigned 16-bit and 40000 (40kHz) respectively to implement 40kHz PTO and PWM functions in Series B controller. Publication 1763-RM001D-EN-P - September 2011...
Page 572 However, since an output frequency can not be a negative value, MicroLogix 1100 controller works properly although the displayed value looks weird. The following table summarizes possible display issues for each different combination of a RSLogix 500 version and MicroLogix 1100 Series. Publication 1763-RM001D-EN-P - September 2011...
Page 573 16-bit signed integer (-32,768...32,767) even though 16-bit unsigned integer (0...65,535) is functionally supported by PTO/PWM. To solve this issue, 2’s complement notation or hexadecimal value should be used. For example, Publication 1763-RM001D-EN-P - September 2011...
Page 574 For example, when a user wants to check if the PTO:0.OF is equal(EQU) 35000 or not equal(NEQ), a user should put 2’s complement of 35000 (-30536) or 88B8h (hexadecimal value) as a specific value as shown below. Publication 1763-RM001D-EN-P - September 2011...
Page 575 32767. For example, assume the PWM:0.OF value is 35000 and the value to compare is 100. Actually, PWM:0.OF is greater than 100, but the executed result of this instruction is just the opposite. Publication 1763-RM001D-EN-P - September 2011...
Page 576 To get an unsigned result without Math Overflow Error from ADD/ SUB/ MUL instructions, S:2/14 (Math Overflow Selected) bit should be set and the S:5/0 (Math Overflow Trap) bit should be cleared after the execution of these instructions. Publication 1763-RM001D-EN-P - September 2011...
Page 577 S:5/0 bit is not cleared after execution of the MUL instruction, then the result will be 32767 and Math Overflow Error will be reported at the End of Scan. ADD Instruction Workaround Example: PTO:0.OF(40000) = PTO:0.OF(20000) + 20000 Publication 1763-RM001D-EN-P - September 2011...
Page 578 How to Use 40kHz PTO/PWM of MicroLogix 1100 Series B Controller MUL Instruction Workaround Example: PTO:0.OF(40000) = PTO:0.OF(20000) X 2 SUB Instruction Workaround Example: PTO:0.OF(20000) = PTO:0.OF(40000) – 20000 Signed 16-bit: 0x9C40 (Hexadecimal) = -25536, Unsigned 16-bit: 0x9C40 (Hexadecimal) = 40000 Publication 1763-RM001D-EN-P - September 2011...
Page 579 JF, OF and OFS of PTO/PWM values are greater than 32767. If PTO:0.JF is 40000, the expected NEG result is -40000 and the expected ABS result is 40000. However, the actual results are 25536 both because both NEG and ABS instruction recognize 9C40h as -25536. Publication 1763-RM001D-EN-P - September 2011...
Page 580 How to Use 40kHz PTO/PWM of MicroLogix 1100 Series B Controller To solve this issue, JF, OF, OFS of PTO/PWM type should be changed to Long Type (32-bit) by CPW instruction before the execution of these instructions as shown below. Publication 1763-RM001D-EN-P - September 2011...
Page 581 32767. All positions are 1 except the far left position. Other examples: 0000 1001 0000 1110 = 2048+256+8+4+2 = 2318 0010 0011 0010 1000 = 8192+512+256+32+8 = 9000 Publication 1763-RM001D-EN-P - September 2011...
Page 582 1s beginning at the left, and subtract its value from the total value of positions to the right of that position. For example, 1111 1111 0001 1010 = (24+23+21) - 28 = (16+8+2) - 256 = -230. Publication 1763-RM001D-EN-P - September 2011...
Page 583 0 to 15. Decimal 0 The position values of hexadecimal numbers are powers of 16, beginning 0 at the right: with 16 Example Hexadecimal number 218A has a decimal equivalent value of 8586. Publication 1763-RM001D-EN-P - September 2011...
Page 584 We know this is a negative number because it exceeds the maximum positive value of 32767. To calculate its value, subtract 16 (the next higher power of 16) from 56950: 56950 - 65536 = -8586. Publication 1763-RM001D-EN-P - September 2011...
