Dear PLC Technical members,
Welcome to our followers on the Blog PLC Technical. Today, we are going to talk about how to upload the Allen Bradley PLC Program via Ethernet cable using Rslogix 500 software. This article provides the skills needed to establish communications with an SLC 505 CPU.
I. How to take a backup from Allen Bradley PLC Program to PC?
Before we look into the communication with the SLC 505 CPU for uploading the Program, let us take a look at Allen Bradley PLC SLC 505 CPU.1. SLC 505 Processor CPU
This one we call CPU or processing central processing unit, where it has a run lamp it means that this view is running now.
FLT: If the Fault pointer is solid red, this generally demonstrates an equipment issue. Flashing red indicates a software flaw.
On the off chance that you have a flashing red FLT light, go online with RSLogix to figure out what caused the deficiency.
FORCE: first it means that some input/output modules or some program has forced.
RS232: This LED will flash as information goes over the RS232 port. This one so green when the correspondence among PC and PLC.
For this CPU it has a three modes, mode run, mode remote, and mode program. For run mode when we like to run mode, it means that we cannot download the program from our computer to the PLC.
Before we start, the following is the rundown of things you need:
Step 1: the hardware requirements
Let's begin by connecting our laptop to Allen Bradley PLC SLC 505 CPU, with the Ethernet cable. A computer or PC can directly connect to channel one on the CPU via an Ethernet cable.
RUN: This just demonstrates your framework is running when the indicator is solid green.
FORCE: first it means that some input/output modules or some program has forced.
RS232: This LED will flash as information goes over the RS232 port. This one so green when the correspondence among PC and PLC.
BATT: battery low inside in the CPU, it has the battery backup for backup the program when the power supply turned off, the battery inside here will working and then support to the ram of the CPU to protect the program loss.
1.1 The Key-Switch for the SLC 505 CPU
When we select remote mode it will the programmer can online, remote, and can start the CPU from the software.
When we select the program mode the CPU will stop and the programmer can download, upload, or do something from the software.
To go online and communicate with an SLC 505 CPU processor, using Rslogix 500 software. There are two ways.
Channel 1: Over the RS232 Port is the Ethernet Port. The Ethernet port can do a lot quicker speeds than the RS232 Serial port.
When we select the program mode the CPU will stop and the programmer can download, upload, or do something from the software.
1.2 The communication protocols used by an SLC 505 CPU
Channel 0: At the base of the processor, you will see an RS232 port. This communication port is used to connect with your Computer, HMI, or different processors. On the off chance that you wish to associate with your PC, you will require an RS232 Null Modem Cable.
- PLC, SLC 5/05 CPU
- PC with Rslogix 500 Software installed
- Programming Cable Ethernet
- Ethernet Hub
2. Procedure to upload Program SLC 505 Allen Bradley PLC
Let's begin by connecting our laptop to Allen Bradley PLC SLC 505 CPU, with the Ethernet cable. A computer or PC can directly connect to channel one on the CPU via an Ethernet cable.
This configuration provides for easing direct communication with an SLC 505 CPU.
Step 2: local area network
To begin with, you should go to a local area network. You need to choose IPv4, and afterward, you need to set up TCP/IP.
Now it's set to obtain an IP address automatically, but since I'm plugging directly from my PC to the PLC there isn't anything to assign an IP. The IP address of our PLC is 10.0.0.5
Step 3: Configuration Ethernet devices
- Configured Drivers: AB-ETH-1, AB Ethernet Running
- Go to the Network 10.0.0.5, SLC 5/05 LINE
Step 4: Open Rslogix 500 software
Go to the tools option system communication, select on Who active option here now we will connect PLC through Rslogix 500 via Ethernet/IP driver, and select on that and click ok.
Now just upload the program from PLC to PC, it will upload the data from a PLC to Rslogix 500 software.
Step 5: save the program
Congratulations You have successfully upload the SLC 505 Processor Program via Ethernet cable using Rslinx classic and Rslogix 500 software.
