    If you force an output controlled by an executing PTOX or PWMX function, an instruction error is generated. Input Filtering The MicroLogix 1400 controllers allow users to configure groups of DC inputs for high-speed or normal operation. Users can configure each input group’s response time. A configurable filter determines how long the input signal must be “on”...
  • Page 30 User Manual. Analog Inputs The MicroLogix 1400 -L32BWAA, -L32AWAA, and -L32BXBA support 4-channel, 12-bit resolution analog input with four 12-bit resolution analog input channels. These channels are single-ended (unipolar) circuits and accept 0…10V DC.

    I/O Configuration Analog Input Filter and Update times The MicroLogix 1400 analog input filter is programmable. The slower the filter setting, the more immune the analog inputs are to electrical noise. The more immune the analog inputs are to electrical noise, the slower the inputs will be to update.

    1200 4095 Analog Outputs The MicroLogix 1400 -L32BWAA, -L32AWAA, and -L32BXBA support 2-channel, 12-bit resolution analog output. These channels have 0…10V DC output range. Output words 4 and 5 contain the value of analog outputs (Word 4 : analog output channel 0, Word 5 : analog output channel 1).
  • Page 33 ----------- - 3000 4095 The MicroLogix 1400 controller provides the ability to individually configure inputs to be latching inputs (sometimes referred to as pulse catching inputs). A latching input is an input that captures a very fast pulse and holds it for a single controller scan. The pulse width that can be captured is dependent upon the input filtering selected for that input.

In contrast to the DF1 Full-Duplex protocol, Protocol communication takes place in one direction at a time.

  • Page 596 efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive Protocol Configuration Message-Based Polling Mode Message-based polling mode is best used in networks when communication with the slave stations is not time critical and where the user needs to be able to limit when and how often the master station communicates with each slave station.
  • Page 597 efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive Protocol Configuration Standard polling mode causes the master station to continuously send one or more 4-byte poll packets to each slave station address configured by the user in the poll list(s) in round robin fashion – as soon as the end of the polling list is reached, the master station immediately goes back and starts polling slave stations from the top of the polling list over again.

This second use is based on the supposition that if a slave station did not respond the last time it was polled, it may not be able to receive and respond to a MSG instruction now, and so it would most likely process the maximum number of retries and time-outs before completing in error.
  • Page 599 efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive Protocol Configuration Addressing Tips Each station on the network, including the master station, must have a unique address. The address range is 0…254, so you can have a maximum of 255 stations on a single telemetry network. Station address 255 is the broadcast address, which you cannot select as a station’s individual address.
