Can the Yokogawa CS3000 have hardware added online?
Thread Content
Due to work requirements, 3 additional cards need to be installed on the Yokogawa CS3000. It is necessary to do this without shutting down the system – is it possible to add hardware while it is running? Are there any good methods or measures?
This is not allowed in order to ensure safe production.
Whether it is a Yokogawa DCS or a DCS from another brand, adding an I/O module will cause the corresponding controller to stop, and all outputs will be set to safe positions; as a result, a series of safety interlocks are inevitably triggered.
Not all DCS systems will experience downtime when hardware is added online. . . 1. Siemens PCS7 uses CiR technology to add IO cards online, without causing downtime at the IO stations. 2. Adding IO cards online to the domestic Xinhua DCS does not cause shutdown. 3. The ABB AC800M can have IO cards added online without shutting down, but this requires a skilled engineer! ABB’s Melody and AC870P do not operate on the principle of installing hardware configurations offline without shutting down the system (usually, adding new IO cards requires modifying the hardware configuration before reinstallation). . This is a truly radical plug-and-play concept. It’s not even in the same order of magnitude. 4. Emerson-WestingHouse allows online addition of IO cards without shutting down the system; the situation for Emerson DeltaV is unknown. . .
Add a card online? In my opinion, if a NODE already exists, inserting an I/O card in an available slot should not affect production; however, adding a NODE while the system is running is likely to be more difficult. It’s better to consult the manufacturer for an authoritative opinion, as it can indeed impact production!
If there are available slots in the NODE, new ones can be added; the CS3000 supports adding them online. It is theoretically possible to expand the NODEs, but it involves risks – after all, safety in production comes first, so caution is necessary!
1. If there is space in the node and only card components need to be added, simply add them, define them in the configuration, and then install them – that’s it. 2. If you want to add nodes online, there are certain risks involved. I’m not sure whether you use the RIO or FIO type; be careful that both redundant buses cannot be disconnected at the same time, otherwise you’ll be in trouble: lol.
Additionally, ABB’s AC400 series DCS allows for the addition of hardware online without any risk, giving peace of mind when using it； Unlike PCS7 CiR, which requires switching controllers, it is quite risky. Last edited by lord82 on 2009-3-3 10:18.]
Cards can be added online to the Yokogawa CS3000 without affecting system operation; for example, the MODBUS communication card ALR121 was added just a few days ago. If you’re concerned that you’ll be prompted to install the card offline after adding it, simply exit the installation process without proceeding with it.
Adding nodes or cards online poses no problem, but the hardware must first be installed before proceeding; one cable should be installed at a time before removing another one – they cannot be removed simultaneously.
Adding a card online should be a piece of cake for the Yokogawa CS3000; I even answered another user’s question a couple of days ago. It is possible to add nodes online. Just be careful with the steps involved. The process of adding a node will be explained using the CS3000 as an example; it’s best to have an engineer from Yokogawa’s service department handle this task, as there are indeed risks involved. The vast majority of tasks in CS3000 can have their configurations modified online. In terms of hardware, this node of yours must be installed at the end, right? OK. Fix the Node, dial in the address, and power it on. Disconnect the existing ESB BUS BUS1 and connect the additional Node; at this point, BUS2 can ensure the normal operation of the original system. Software configuration: add a new node and download it. Once the new Node is working properly, disconnect BUS2 and connect it to the new Node. Okay, it’s all done. In short, only one BUS can be disconnected at a time; never disconnect two of them simultaneously. Once again, there is a risk: it is possible that BUS2 could also fail at the exact moment you disconnect BUS1. Have the process technicians do some preparatory work during operation.

I disagree with you. It can be clearly stated that the HONEYWELL TDC3000 or TPS systems allow for the addition of cards online – all that is needed is to access the relevant settings, make the necessary modifications, and then reinstall the cards. This process has no impact whatsoever on the controller. I have done this kind of work numerous times, and I have never encountered any problems.
