Page 157: Noise Occurrence
D50 PLC User's Manual Noise Occurrence Types of Noise • Radiation noise is transmitted in the form of a magnetic wave. The amplitude of the magnetic wave is measured in Gauss. • Conduction noise is transmitted through a direct path such as signal wiring or ground connections as a strong, high-voltage surge.
Page 158: Sources Of Noise
There are three main sources of noise. Some of these sources generate large noise amplitudes. The occurrence time can be very short (impulse type) or continuous (power line induced). Some noise levels can damage the D50 PLC components and peripheral devices. Noise Generated by Electronic Equipment All electronic devices radiate noise in the form of a magnetic field.
Page 159: Advised Installation Practices
D50 PLC User's Manual Advised Installation Practices Shield the PLC The most common method of shielding, is to install the PLC inside a grounded steel enclosure. Proper Cable Selection Use twisted, shielded-pair cable for the power cable and field wiring. Properly terminate the shields of all cables to a single-point high-quality ground.
Page 160: Isolation And Filtering Techniques
Chapter 8: Troubleshooting Noise Problems Isolation and Filtering Techniques Isolation There are several methods of isolation: • Attach an isolation transformer between the PLC power supply and the VAC source to help remove noise that flows in the power cable. Try to attach the isolation transformer as near to the PLC power supply input terminal strip as possible.
Page 161: Filters
D50 PLC User's Manual Filters Filters should be used to suppress high frequency noise. When using a low-pass filter specify one that is designed for power line applications. Many different types are available from simple modules to complex units. A single device is not necessarily the most cost-effective device for all applications. In specifying the proper filter one must take into account the amplitude/power level of the noise and how often the noise is present.

Page 166: Warning
Chapter 8: Troubleshooting Noise Problems Warning The following two protection methods should be avoided. Each of these methods can be effective in removing the sparks when power to the inductive load is turned off. However when power is turned on to the inductive load there will be a high inrush current applied across the relay contacts as they are mating.
Page 167: Troubleshooting
D50 PLC User's Manual Troubleshooting • Noise from magnetic fields induced by other electrical/electronic equipment onto the PLC can be avoided by relocating the PLC during the design process, installing the PLC in a grounded steel enclosure, or attaching a filtering or suppression shield/circuit to the device which is generating the magnetic field.

To handle the requirements of configuration and operation of the special function I/O, the D50 provides 21 special I/O function registers. These registers are assigned to the various functions, and are programmed and edited by the user in the D50 PLC ladder program. The purpose of each individual register is outlined below.
Page 189: High Speed Counter
D50 PLC User's Manual High Speed Counter The D50 PLC provides two 24-bit, 10kHz high-speed counters (on the DC-input units only). Each of the two counters functions identically to the other. Each has a set of 7 registers allocated for its configuration and operation, plus an additional comparision register that they share.
Page 190: Bit Registers
Appendix B: Special I/O Functions Bit Registers Three of the configuration registers used by the high-speed counters are bit registers – each bit in the register serves a different purpose. The three bit registers and the individual bit meanings are described in further detail below.
Page 191: Programming Procedure
For this example, a standard Up Counter is programmed, with an end value of 100. At the count of 9000, the program turns on the D50 PLC’s first output R15.0, and at the count of 10000, the second PLC output R15.1 is turned on. Since this is an Up Counter, the first input of channel 0 is used to count input pulses.
Page 192: Configurable Input Response Delay
Appendix B: Special I/O Functions Configurable Input Response Delay The special I/O function register FTIME (R27) controls the amount of time that an input must remain on before the input state is changed in the PLC I/O map. This amount of time is called the “Input Response Delay”, and affects all eight inputs on the controller module (R0.0 to R0.7).
Page 193: Pulse Catch Input
PLC is of very short duration, often less than the scan time of the PLC. To allow the user program to detect those types of short-duration input signals, the D50 allows any or all of the digital inputs on the controller to be configured as “Pulse Catch”...
Page 194: Pulse Output
Appendix B: Special I/O Functions Pulse Output The D50 PLC provides two modes of Pulse Output on the first output contact of the controller. The first mode, Pulse Mode, sends out a given number of pulses at a user-defined frequency. The second mode, PWM (Pulse Width Modulation) Mode, sends out a continuous stream of pulses, at a user- defined frequency and duty-cycle.
Page 195 D50 PLC User's Manual PSV (R013) The PSV register is defined by the Mode of operation. In Pulse Mode, the PSV register holds the total number of Pulses to be sent out, from 0 to 65,535. When set to 0, the pulse output is continuous. In PWM Mode, the PSV register holds the duty cycle of the pulse, from 0 to 100%.
Page 196: Pulse Mode Programming Procedure
The following ladder program illustrates the above procedure by configuring a Pulse Output on the D50 PLC. The Pulse Output is set to send out exactly 200 pulses at a frequency of 50Hz, when the PLC is first placed into RUN.
Page 197: Pwm Mode Programming Procedure
The following ladder program illustrates the above procedure by configuring a PWM Output on the D50 PLC. The PWM Output is set to continuously send out pulses at a frequency of 50Hz and a duty cycle of 25%, when the PLC is first placed into RUN.
Page 198: Appendix C: D50Pgm10 Pocket Editor

Page 200: Part Descriptions
The SHF LED provides visual feedback that the user has pressed the shift (SHF) key. • The RUN LED indicates when the D50 PLC is in the RUN mode. • The ON LED indicates when a given contact or output point is turned On, when monitoring and instruction or bit register.
Page 201: Register Led's
There are 12 instruction keys on the pocket editor that are used for entering the 25 basic instructions on the D50 PLC. To enter certain of the basic instructions, more than one of the instruction keys may be combined. Refer to the Basic Instruction table at the end of this appendix for details.
Page 202: Function Keys
Appendix C: D50PGM10 Pocket Editor Function Keys There are 8 function keys on the pocket editor, plus two functions that are accessed using the SHF key. The 10 functions each have multiple uses, based on the mode of operation the pocket editor is being used in.

Page 213: Error Checking
D320 PLC User's Manual Error Checking The D50 has built-in error-checking routines that can check the PLC program for syntax errors such as multiple output coils using the same reference, invalid coil addresses, and so on. The D50 pocket editor can request an error check from the D50 PLC using the SHF and CHK keys.
Page 214: Monitor I/O
Appendix C: D50PGM10 Pocket Editor Monitor I/O There are two types of monitoring that the pocket editor can perform. The first type is bit monitoring, which displays the state of a given contact or coil in the program. The second type of monitoring is register monitoring, which displays the 16-bit value of any user-specified register address.
Page 215 Any valid register address can be monitored using the register monitor mode of the pocket editor. In this mode, the register is continuously updated from the D50 PLC, and can be changed by the user. To enter the monitor register mode, press the SHF key, the register address, and then the MON (DIF) key.
Page 216 Force Outputs The states of output coils can be forced On or Off in the D50 PLC. The output to be forced must be an output that has been programmed in the PLC. The SET and RST keys are used for Force On and Force Off, respectively.
Page 217: Run/Stop Plc
When the RUN/STOP switch on the D50 PLC is in the RUN position, the mode can be overridden by the pocket editor. To place the D50 PLC in STOP, press the INS key, followed by the RST key. To return the PLC to the RUN mode, press the INS key followed by the SET key.
