  • Page 15 Chapter 2: Installing a ControlLogix 1756sc-CTR8-SC Module This equipment is classified as open equipment and must be installed (mounted) in an enclosure during operation as a means of providing safety protection. The conformally coated versions of the module meet or exceed the ANSI/ISA 71.04.2013 G3 Environment standard.
  • Page 16 Chapter 2: Installing a ControlLogix 1756sc-CTR8-SC Module Hazard of electrical arcing when removing or inserting the module WARNING while power is applied to the rack. This module is designed so you can remove and insert it under backplane power and field-side power. When you remove or insert a module while field-side power is applied, you may cause an electrical arc.
  • Page 17 Chapter 2: Installing a ControlLogix 1756sc-CTR8-SC Module Key the RTB to prevent inadvertently making the wrong wire connections to your module. Use a unique keying pattern for each module. You can use a minimum of one key. When the RTB mounts onto the module, keying positions will match up. For example, if you place a U-shaped keying band in position #4 on the module, you cannot place a wedge-shaped tab in #4 on the RTB or your RTB will not mount on the module.
  • Page 18 Chapter 2: Installing a ControlLogix 1756sc-CTR8-SC Module Follow these guidelines to wire your input signal cables: • Power, input, and output (I/O) wiring must be in accordance with Class I, Division 2 wiring methods [Article 501-4(b) of the National Electrical Code, NFPA 70] and in accordance with the authority having jurisdiction.
  • Page 19 Chapter 2: Installing a ControlLogix 1756sc-CTR8-SC Module To prepare and connect cable leads and drain wires, follow these steps: 1.

  • Page 24 Chapter 3: Operation Within the ControlLogix System Even though data may be transferred at the RPI rate, the data will be NOTE identical to the previous RTS data transfer. If an input module resides in a networked chassis, the role of the RPI and the module’s RTS behavior change slightly with respect to getting data to the owner.
  • Page 25 Chapter 3: Operation Within the ControlLogix System Choosing a Listen-Only mode option allows the controller and module to establish communications without the controller sending any configuration data. In this instance, another controller owns the module being listened to. IMPORTANT: Controllers using the Listen-Only mode continue to NOTE receive data multicast from the I/O module as long as a connection between an owner and I/O module is maintained.
  • Page 26 Chapter 3: Operation Within the ControlLogix System Exercise caution when changing an input modules’ configuration data in a multiple owner scenario. When the configuration data is changed in one of the owners, for example, Controller A, and sent to the module, that configuration data is accepted as the new configuration for the module.

This chapter outlines the detailed settings for the 1756sc-CTR8.

  • Page 36: Section 5.4 Uni -Directional

    Chapter 5: Configuration, Data, and Status Tags The following Global Module Settings and Channel-Specific Settings sections allow custom configuration of the module. These tags can be found within the CTR8_config controller tags. [x] designates the channel number. (C) designates the value may be changed during module operation CountLimit[x] 0 - 16777215 FLOAT (C) Designates the channel rollover value.
  • Page 37 Chapter 5: Configuration, Data, and Status Tags With this configuration, the input increments in an upward direction. All 8 channels may be configured in the unidirectional mode. Every clock pulse will increment the counter on the rising edge. The direction of the counter may be inverted by setting the Count NOTE Direction bit described in the Configuration chapter.
  • Page 38 Chapter 5: Configuration, Data, and Status Tags If B leads A, the counter decrements. However, the counter changes value on the rising and falling edges of inputs A and B. The counter increments four times per quadrature cycle. This mode determines how the gate behavior effects counter behavior: 0 = no store mode.
  • Page 39 Chapter 5: Configuration, Data, and Status Tags StorageMode = 2 - Store/Wait/Resume. StorageMode = 3 - Store-Reset/Wait/Start. StorageMode = 4 - Store-Reset/Start. InputRange[x] 0,1 This setting determines the threshold where the counter will begin to trigger. Select the range that is best suited to your sensor’s range: 0 = AC 50 mVpp threshold.

    Chapter 6: Programming Examples points, a start and a stop. A pulse trigger caused by a ball crossing a proximity switch zeros the counter and starts the accumulation. When the ball reaches the end of the run, another pulse occurs stopping and storing the accumulated value. If the input device is an open collector type it may be necessary to use a pull-up or pull-down resistor in order to achieve the proper threshold crossover point.
