does anyone have any example code or experience using the RHC and TDF commands? i need to calculate speed based off of and input pulse. i know what the diameter, tooth count and pitch are of the gear i'm measuring and also have to relate this to the diameter of another gear. i'm hoping Ken Roach has some words of wisdom, i do appreciate advice from anyone. Thanks in advance.
I am trying to learn how to use add-on instructions, and to get a better understanding I am trying to do a simplified example. I am trying to make two separate add on instructions that alter an integer tag in different ways. I would like one AOI that multiplies the input integer by 3 and another AOI that adds 3. The integer tag is a InOut parameter. I named these AOIs "Mult3" and "Add3". When trying to use the AOI's it requires me to have an additional input with datatype the same as the AOI ("Mult3" or "Add3"). I have a couple of questions about this: 1. Why is this data type required? It seems to me that I would only need the InOut integer that I want to modify. 2. I want to use these AOI's in a number of places throughout my code on a number of tags. Would I be able to just use one "Mult3" tag for all the AOI's, or would I need a seperate tag for each use of the AOI? For Instance if I am using the Mult3 AOI in 3 separate places in my code, two times using "Int1" as the InOut parameter and another time using "Int2" as the InOut parameter, could I just make one tag of "Mult3" datatype and use that for all the instances of the AOI, or would that screw it up in some way. Thanks for any help.
PAROCK1 for HMI/SCADA View File Now a software solution is available for your Modbus (MB) needs in Rockwell/Allen-Bradley Control Logix or Compact Logix (Clgx) family processors, instead of a traditional 3rd party hardware like Prosoft MVI-56, Molex SST-SR4-CLX-RLL etc. It is an Add-on instruction (AOI) for PLC/PAC firmware v16 or later, (other solutions are available for pre v16 systems). For hardware interface, use PLC’s channel 0 (serial) or TCP/IP Interface module(s) to have as many MB TCP/IP devices or serial devices. (Some limits apply based on system configurations, Comm. settings depending on HW used.) Connect any MB Client/Master or Server/Slave device(s) to your CLgx PLC, including flow computers, analyzers, VFDs, Power Monitors, Level gauges, Smart I/O, etc. All the MB public/native function codes are supported. 32-Bit integers/floats as single entity are supported with byte and word level swapping. A separate utility automates the data mapping to your PLC logic. Features -Serial Master (BASIC required Option); TCP; Slave; Redundancy; More than 5000 accumulative registers; MB CFC (Custom/Private Function Code) Support; Data mapping too – Between PAROCK1 & your PLC logic; Packaged with Rockwell; TCP/IP Interface Module; Volume Discounts; Annual Support Requirements -Rockwell/AB-CLgx processor with v16 or later. Contact PCI for earlier versions. -If using CPU’s Chan0, you cannot use Chan0 for any other user mode activity. You can use it for non-user mode activities -TCP/IP Interface Modules from Rockwell/AB supported, are: -1756-EN2xx ControlLogix® Ethernet/IP communication modules, firmware revision 5.007 or later -1756-EWEB ControlLogix Ethernet/IP web server module, firmware revision 4.006 or later -1768-EWEB CompactLogix Ethernet/IP web server module, firmware revision 1.002 or later -1769-L30ER, 1769-L30ERM, 1769-L30ER-NSE, 1769-L33ER, 1769-L33ERM, and 1769-L36ERM CompactLogix controllers, firmware revision 20.011 or later -1769-L24ER-QB1B, 1769-L24ER-QBFC1B, 1769-L27ERM-QBFC1B CompactLogix controllers, firmware revision 20.011 or later -1769-L16ER, 1769-L18ER, 1769-L18ERM CompactLogix controllers, firmware revision 20.011 or later Other Related Services/Items -Custom PLC Add-on instructions building -PLC upgrades, troubleshooting, applications -PC Windows, iOS5, Linux, Mobile devices Comm. Drivers -Custom development, Technology Transfer Services -Other Non-AB communication drivers for serial or TCP -Full control system integration, training, architecture design This driver can be conviniently used with Visual Studio in development of complete large scale complex HMI/SCADA Systems.

I've got one rung set up using a UDT and simple logic. The purpose of this rung is to write a string to a tag, which will be sent to the HMI later. Since RSLogix 5000 refuses to allow my AOIs to export any string value, or string tags, I can not figure out how to utilize add-on instructions to easily replicate this logic. Any ideas on how to make this work?
