CompactLogix Packaged Controllers Catalog Numbers 1769-L23E-QB1B, 1769-L23E-QBFC1B, 1769-L23-QBFC1B
IMPORTANT The series B controllers are compatible only with the controller firmware and the RSLogix 5000 software versions as indicated in the table below. Attempting to use controllers with incompatible software and firmware revisions can result in the following: • An inability to connect to the series B controller in RSLogix 5000 software • Unsuccessful firmware upgrades in ControlFLASH™ or AutoFlash utilities
In this example, these expansion I/O modules and bus current draws are planned for use with the 1769-L23E-QBFC1B packaged controller.
The total bus current draw of the Compact I/O modules (310 mA) is less than the total available bus current of the packaged controller (450 mA). These planned expansion I/O modules are within the limits of the 1769-L23E-QBFC1B packaged controller.
Panel Mount the System To mount your system to a panel, complete these steps. 1. Using the assembled system as a template, carefully mark the center of all mounting holes on the panel. 2. Remove the system and drill and tap the mounting holes for the recommended M4 or #8 screws. 3. Place the grounding panel (if used) and CompactLogix system on the panel to check for proper hole alignment. 4. Insert the recommended screws into the mounting tabs on the packaged controller and expansion modules (if used) and tighten
To begin wiring your embedded I/O removable terminal blocks, loosen the screws at the top and bottom of the removable terminal block and remove the removable terminal block from the packaged controller.
• All analog I/O commons (ANLG COM) are connected in the analog I/O card of the packaged controller. The analog common (ANLG COM) is not connected to earth ground inside the packaged controller. • Analog I/O channels are not isolated from each other. • Use Belden 8761 (or equivalent) shielded wire. • Under normal conditions, the drain wire and shield junction must be connected to earth ground via a panel or DIN rail mounting screw at the analog I/O removable terminal block end. Keep the shield connection to ground as short as possible. • To ensure optimum accuracy, limit overall cable impedance by keeping your cable as short as possible. Plan to place the packaged controller as close to your sensors or actuators as your application permits.(1) • If multiple power supplies are used with analog inputs: • the power supply commons must be connected. • do not exceed the specified isolation voltage. • The embedded analog I/O does not provide loop power for analog inputs. Use a power supply that matches the input transmitter specifications. • Differential analog inputs are more immune to noise than single-ended analog inputs. • Voltage outputs (Vout 0+ and Vout 1+) of the analog I/O are referenced to ANLG COM. Load resistance for a voltage output channel must be equal to or greater than 1 K. • Current outputs (Iout 0+ and Iout 1+) of the analog I/O source current that returns to ANLG COM. Load resistance for a current output channel must remain between 0…300 . • Voltages on Vin+, V/Iin-, and Iin+ of the analog I/O must be within 0 to +10V DC of analog common.
• Input and output channels are isolated from the packaged controller. Input channels are isolated from one another; output channels are not. • Shielded cable is required for high-speed input signals A, B, and Z. Use individually shielded, twisted-pair cable (or the type recommended by the encoder manufacturer) for lengths up to 300 m (1000 ft). • Route field wiring away from any other wiring and as far as possible from sources of electrical noise, such as motors, transformers, contactors, and AC devices. • Routing field wiring in a grounded conduit can reduce electrical noise. • If field wiring must cross AC or power cables, ensure that they cross at right angles. • Make sure the system is properly grounded using these guidelines: – This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the packaged controller’s mounting tabs or DIN rail (if used) are only required when the mounting surface is non-conductive and cannot be grounded. – Keep the shield connection to ground as short as possible. – Ground the shield drain wire only at the HSC input end, except where high-frequency noise is present.
Digital Inputs Status Indicators There is one status indicator for each digital input point of the CompactLogix packaged controller. When an input is ON, the corresponding input light is on (amber). Digital Outputs Status Indicators There is one status indicator for each digital output point of the CompactLogix packaged controller. When an output is ON, the corresponding output light is on (amber). Analog I/O Status Indicator The analog I/O have one status indicator - the OK status indicator. If the indicator is green, the analog I/O have power, have passed internal diagnostics, and are communicating properly. If analog I/O OK indicator is off, a fault is present. High-speed Counter Status Indicators The high-speed counters have 12 status indicators.
