If you need more, let me know and i'll share what worked out for me. in this instance I have the number 1 in cell i1 and it writes a 1 to my plc bit named Reset_Pointer, this is a dint. The is the cell in the excel spread sheet that I chose to hold the data I wanted to write the the PLC. RSIChan = DDEInitiate("RSLINX","F2905_Snap")ĭDEPoke RSIChan, " Program:MainProgram.Reset_Pointer", In this instance, the topic is F2905_Snap, and Program:MainProgram.Reset_Pointer is the tag that I am writing to. This generally runs every morning at 4am and is automated by a function within the application. This is all done in the dev section of excel, I have a button that triggers this on the main page so I can trouble shoot it as needed. Of course you will need rsLinx OEM and set up the topic for your PLC. This is what I use to write a value to my plc after I pull all the data I wanted.

In logix 5000 I can't assign a DINT tag to a timer preset so I have to MOV the DINT to the timer.pre. Step 1 Create a line of ladder and in the instruction palette under Input/Output, choose a GSV Instruction and set up the following: Class Name: WallClockTime Attribute Name: DateTime Dest: CurrentTime 0 (This is a tag you will create, DINT type with an array of 7) Image by Brandon Cooper Step 2 Write your logic changes. While many Allen-Bradley PLC products will have firmware already installed, makes no representation as to whether a PLC product will or will not have firmware and, if it does have firmware, whether the firmware is the revision level that you need for your application. In Logix 500, you can assign an integer file to a timer preset so that multiple timers can have the same preset and they can all be changed quickly and at the same time by adjusting the integer value.

However if your HMI does not support range limiting then better practice is to write to an N word and include logic to make sure that a valid preset has been entered. So depending on what LCD/keypad you are using you can probably write directly to the preset word of your timer memory. You can also program most HMI devices such as a Panel View, or the Redlion G3 or the C-More, and many others, to write directly to any desired word address of not only N files but also any word of a T file, C file, R file, etc. Remember to Turn captions on and subscribe DHow to use TON (Timer ON Delay) timer in rslogix 5000 / Studio 5000 - 2021 - With a sample usecaseFollow us: htt. All tags must be Controller Scoped for data. You could also leave it at 0 and have that word in memory written to programatically. Using RSLogix / Studio 5000 software configure a Ladder Logic file as shown in. You can pre program that word to be a particular value when you enter the timer instruction. PRE is a shortcut supported by the programming software to enforce strong data typing. The preset in any time structure is at the memory address TX:X.1. The timer preset is one of the words in the timer data structure located in memory, just like an integer (in fact it is an integer). The AB supports strong data types, and a T file is a section of memory where the words are divided into three word groups for use by a timer instruction. It is a computer instruction that operates on a section of memory. Style is the form in which to display the tag by default. It is data memory, its not anything else. Earlier Allen Bradley PLCs programmed with RSLogix 5 and RSLogix 500 software had data files.
