Are you facing challenges in acquiring analog input and output cards for your customers with specific point requirements? In such cases, have you come across any readily available Ethernet armor blocks or remote I/O solutions that can fulfill these needs? It can be frustrating to delay projects for months due to unavailability of necessary components. Opting for remote blocks often proves to be a viable solution. While the used market may not be feasible, as prices are inflated, it's worth exploring alternative options to cater to analog requirements, especially when the digital options fall short.
Welcome to our forum! We rely on Ethernet based I/O devices provided by Murr, particularly from their Cube67 product line. Murr's products are known for their quality and excellent customer support. You can find more information about the Cube67 line on Murr's website: https://www.murrelektronik.com/products-industries/products/io-systems/detail/product/cube67. Please note that we source our Murr products from Buchanan Automation.
I have been using an Automation Direct thermocouple module with my CompactLogix PLC for several months now, and it has been working perfectly. I have a feeling that their other analog modules would also perform just as well. However, it seems like they won't be available until late April. Check out their website for more information on the SIO-MB08THMS analog module.
Hello and welcome to the forum! We utilize Ethernet-based I/O devices from Murr, specifically the Cube67 line. Their products are of high quality and backed by excellent customer support. You can find more information about their products at https://www.murrelektronik.com/products-industries/products/io-systems/detail/product/cube67. We source our Murr products from Buchanan Automation. Have you considered using it with IO Link?
In a recent forum post, user johnd_125 shared their positive experience with an Automation Direct thermocouple module connected to a CompactLogix PLC. They mentioned that the module has been working flawlessly for a few months, and expressed optimism that other analog modules from the same company would perform just as well. However, it appears that there may be a delay in availability until late April. The product in question, a modbus TCP-enabled module, can be found at the link: https://www.automationdirect.com/ad..._i-z-o/stride_i-z-o/analog_i-z-o/sio-mb08thms. It was also noted that similar analog modules are available, although with a later availability date in June. The original post also raised the question of whether the module is compatible with the ethernet port on the CompactLogix PLC.
Davinjw commented that the devices appear to be high-quality and also available in regular analog versions (until June). The one in the provided link is specified as utilizing Modbus TCP. Are you implementing this with the Ethernet connection on the CompactLogix PLC? Yes, I am connecting it via Ethernet, necessitating the use of a "Modbus TCP Client" Add-On Instruction (AOI) in the CompactLogix. This instruction is named "raC_Opr_NetModbusTCPClient," as shown in the attached image.
Indeed, the scarcity of specific analog input and output cards has been a real hurdle. One solution I've found is leveraging modular I/O systems like Beckhoff's EtherCAT Terminals or Siemens ET200 series. Not only do they provide a wide range of I/O modules, but their flexibility allows you to pick and choose the exact modules required for your application needs. Plus, their integration to PLCs via Ethernet makes them a very competent substitute for the traditional cards we are used to. It's amazing how these modern systems can eliminate the need for monolithic I/O cards and essentially expedite project timelines. It's like building with Lego blocks; you just snap together the pieces you need!
I totally relate to the struggle of sourcing analog input and output cards; the lead times can really throw a wrench in project timelines. I’ve been exploring some remote I/O solutions too, and I've had good luck with Ethernet-based armor blocks that are meeting our specific needs without breaking the bank. It seems like manufacturers are starting to focus on more flexible remote options, so it might be worth checking out some newer models that can handle analog signals without the traditional delays. While the used market is tricky, I think investing in reliable new tech might save us more headaches in the long run!

Answer: Answer: Ethernet armor blocks are modular devices that can provide analog input and output capabilities for Compactlogix systems over an Ethernet network. They offer a convenient and flexible solution to meet specific point requirements.
Answer: Answer: Remote I/O solutions allow for the decentralization of analog input and output functions, enabling users to easily expand their system's capacity without being limited by the physical constraints of the main controller. They offer a scalable and efficient way to fulfill specific point requirements.
Answer: Answer: While the used market may have inflated prices and limited availability, exploring alternative options such as Ethernet armor blocks and remote I/O solutions can provide a reliable and cost-effective way to meet analog input and output requirements without depending on used components.
