Allen Bradley 1785 L80C15

The old production line was upgraded from DH+ to ControlNet. The most troublesome part was that the program needed to be rewritten and a new set of devices had to be installed. Feimu Technology, as a high-quality supplier with a long history of specializing in industrial control upgrades, is well aware of this hassle. This Allen Bradley 1785 L80C15, with a PLC-5 architecture, retains the original essence of the program and can directly transfer without the need for rewriting; it has a built-in ControlNet 1.5 high-speed interface with a 0.5ms deterministic scan, and can operate in a mixed network setup with both old and new networks; with 100K of RAM and 125 chassis expansions, the upgraded performance can even reach a higher level.

For the transformation of old production lines in industries such as automobiles, metallurgy, and chemicals, simply replacing the processor will do the job.

FAQ

Q1.what is the difference between 1785 L80C15 and 1785 L80B?

Both belong to the PLC - 5/80 series processors, but the specific differences involved hardware version, communication configuration and application environment, should confirm according to the system configuration.

When selecting, one should check: the original processor model; communication network; system configuration; program compatibility.

Q2. What communication modes are supported? The main support PLC - 5system communication, including:

The Data Highway Plus (DH +)

Remote I/O

The actual support depends on the system architecture.

Q3. What software is used for programming?

Use RSLogix 5 software for:

Program editing

Upload/download

Online monitoring Fault diagnosis

Q4. Do we need to rewrite the program after the replacement?

Usually, there is no need to redevelop the program.

If there is a backup program:

Download the original PLC program,

Set the communication parameters,

Check the I/O configuration,

Perform a running test;

Then the system can be restored.

Q5. How to determine if there is something wrong?

Check the CPU state of lamp

Test the PLC communication

Verification program run

Check the I/O response

The inspection process

Appearance check:

Confirm the product model, label, shell, interface is complete, no obvious damage.

Model validation:

Check the Allen Bradley 1785 L80C15 model, hardware information and PLC - 5 system compatibility.

Electric test:

Check the module power status, CPU running status and indicator light display.

Feature test:

Test running, application processor, speaking, reading and writing and PLC communication function.

Communication test

Verify that DH+, Remote I/O and other communication connections are normal.

Shipment Check:

Record test results, product photographs and anti-static, shockproof packaging shipments.

Installation Process

System to confirm:

Confirm that PLC-5 rack, power module, communication network and module model match.

Power operation:

Turn off the power supply of the control system to ensure a safe installation environment.

Module Installation:

Insert the 1785 L80C15 processor module PLC - 5 frame corresponding to the slot, and fixed connection.

The line with communication
