【英文介绍】
The Allen-Bradley 1756-L81ES controller is the Allen-Bradley GuardLogix 5580 safety controller. It can perform 31 standard tasks and 1 security task. Each task supports 1000 programs. Integrated communication ports on the 1756-L81ES controller include a USB port and an Ethernet port. The USB port is USB 2.0 compliant and supports a 12 Mbps data rate. Ethernet ports can support data rates of 10/100 and 1000 Mbps. Optional communication modules for the 1756-L81ES controller include ControlNet, DeviceNet, Remote I/O, DH+, and SynchLink modules. The maximum number of Ethernet /IP nodes supported is 100.
The 1756-L81ES controller supports the following programming languages: ladder diagram, structured text, function block diagram and sequential function diagram languages. Controller redundancy is not supported. The user memory capacity on the module is 3 MB and the safe memory capacity is 1.5 MB. The maximum number of digital and analog I/ OS supported is 128,000 and 4000 respectively. The 1756-L81ES controller can support a total of 128,000 I/ OS. The module comes with 2 GB of integrated non-volatile memory. The module consumes 5 mA at 1.2 volts DC and 1.2 amps at 1.5 volts DC. The power dissipated as heat during operation is 6.2 watts. The module weighs approximately 0.394 kg. The 1756-L81ES controller requires an empty slot in the chassis for installation. Chassis compatible with the 1756-L81ES include the 1756-A4, 1756-A4K, 1756-A7, 1756-A7K, 1756-A10, 1756-A10K, 1756-A13, 1756-A13K, 1756-A17, and 1756-A17 K B Series and C Series chassis. Operating temperature range is 0 to 60 degrees Celsius.
The Allen-Bradley 1756-L81ES is a GuardLogix controller with 3 MB of integrated user memory and 1.5 MB of safe memory, similar to the ControlLogix controller, which has a maximum I/O capacity of 128,000. It has integrated communication ports for USB and Ethernet.
Unlike the ControlLogix controller, this GuardLogix controller has 1756-SD2 integrated removable memory, which is the only compatible memory for this controller module.
This module supports a wider range of chassis. Although this is a GuardLogix controller, it can be installed in standard and random ControlLogix cases, For example, 1756-A4, 1756-A4K, 1756-A7, 1756-A7K, 1756-A10, 1756-A10K, 1756-A13, 1756-A13K, 1756-A17, 1756-A17 K series B, C series. It can also be used with a wider range of power modules, Such as 1756-PA50, 1756-PA72, 1756-PA72K, 1756-PA75, 1756-PA75K, 1756-PB50, 1756-PB72, 1756-PB72K, 1756-PB75, 1756-PB75, 1756-PH75, 1756-P C75.
This module supports redundancy using the ControlLogix redundancy module. For this high availability requirement, compatible power supplies are 1756-PA75R, 1756-PA75RK, 1756-PB75R, 1756-PB75RK, 1756-PSCA2, 1756-PSCA2K.
It has an intuitive diagnostic display that provides a text description of the status of the module.
With this controller, Safety Instrument Class (SIL) 2 is achieved. This module supports a mix of standard ControlLogix and secure I/O, and can also implement topologies that standard ControlLogix can support.
