Hello I've used 2 Omron ZX1 lasers (above and below) for an application very similar to yours. Pp

Hello I have CX-one installed on two machines. Both are mine and no one else has access. If it's so two people can use it, then yes you can, but no you shouldn't. Pp

Hello If you add the correct junction slave, the nodes can be dragged onto it from the erroneous one; no need to delete and the IO mapping is maintained. Pp

Hello If you're using the automatic allocation (modes 0, 1, 2 or 3) then I think the analog card will want 2 nodes. Try making the node numbers with a gap between (1, 4, 8 etc). If you're using mode 8 (ie mapping the IO with CX-Integrator) then you can set the node numbers as you like Pp

I see. Thanks

Which market is this aimed at?

Hi Andy I grounded at one end only. The remote panels were a good distance away, so ground may well have been at a different potential. These outlets are more suited to terminating installation cable (solid cores). They may have something suitable for in-panel use. Just be sure to get a 360 degree wrap on the shield, and no shield pigtails! Pp

Ethernet outlets (Phoenix sell them) do this job. Depending if the EtherCAT nodes are local or remote determines if the shield is grounded or not (there's a plug you can remove to insulate from the DIN rail). I had long cable ecat runs to remote I/O recently, and these things were a silver bullet. Pp

Hello BnB IMO, it's not worth the trouble, and doesn't give great results. I'd use the RX's own positioning and either select positions with a binary pattern, or if the positions need to change pass it through Modbus. I've done this a few times. The Omron-created Modbus FBs do this well. The RX is possibly the worst inverter in the world to use, but the positioning works pretty well. Regards, Pp

Hello Jack No documentation, I'm afraid, other than the program. If you have CX-P then you may be able to follow the FB I wrote. Let me know if you want it - pm me an email address. The CP1H is more than adequate for what you describe. As I said, a CP1L has no major disadvantage in this type of application. I see you're in the UK - our Omron support is unsurpassed. Pp

Your topic title asks for the right PLC. The CP1L family will suffice for this job. That said, I'd dig deeper and choose CJ2; more expensive but more HP. Are the vac pumps inverter driven? Is the vac feedback a switch or an analog signal? Location of above drives/feedback? I've done a few cooling tower jobs with 6 or 8 fans, with the same ideas you've asked for. The principles would be much the same. Probably. Pp

+1 for this. The screen name is available as a String in _HmiCurrentScreen (or something like that). Maybe a NJ STRUCT could be automatically created as screens are added?

Sergei. I've used it. From manual W487-E1-14: The Synchronous Data Link function is available when the CJ1W-NC82 PCU (unit version1.3 or later) is used in conjunction with a CJ2 series CJ2H-CPU CPU Unit (unit version 1.4or later).In addition, when used in conjunction with a G5-series R88D-KN-ECT Servo Drive (version2.0 or later), the PCU can provide speed control (CSV)/torque control (CST) based on controlcommands updated in the Synchronous Data Link Area.The PCU also supports the Electric Shaft function (CSP) that performs synchronized axis controlbased on the multiplication factor configured for any axis in the same unit.

The Nc card can in fact do torque control. You need to use a CJ2H though. The CJ2M is, as Sergei says, position only. Pp

If it's just the address that changes, then the address can be specified indirectly. From memory, there are 9 index registers. Suffix the address with 'i0' (for example). The index registers are mapped to $SW memory ie can be mapped to the plc. The value in the index register can be calculated from the current screen number. Or simply have one screen with a button, for instance, to adjust the index register. I use the Frame object to great effect with this sort of thing as the current tab number can be used to derive the offset. Pp

I use this FB for 'long' times. It brings in a couple of other FBs. Just create instances of HHMMSS as you need them. You can give it any H, M, S (eg 99 mins 500 seconds if you want). The time remaining it gives you is normalised as H, M and S as INTs which can be easily displayed. http://forums.mrplc.com/index.php?/files/file/1025-hhmmsscxf/ Pp

File Name: HHMMSS.cxf File Submitter: ParaffinPower File Submitted: 08 Dec 2014 File Category: PLC Sample Code FB to provide a simple long timer with time remaining outputs. Time can be entered in HMS (or just mins for example). Time remaining is normalised to HMS though. Uses 2 other FBs. Create instances of HHMMSS as required. Click here to download this file

I'm thinking the time to reply in cx-protocol. From memory it's called Tfs.

The protocol macro error flag will come on if it doesn't get a response within a time. (Tfs from memory???)

+1 for the mouse-over datatype - appears in ST already but not ladder annoyingly.

NJ firmware is field upgradeable. Part number NJ301FW109STD gets you an SD card. Omron can do this for you, aswell. Pp

1. Faster switching between NA/NJ environment. 2. NA symbols NEED to be HostName.SymbolName and not the concatenated name SS assigns. In fact, it's a pain that it needs separate names at all. Makes serial machines with different CPU names impossible. 3. Ability to dynamically disable or change visibility of a button in its properties rather than resorting to VB. 4. Online operations (going online, offline, online edits) are too slow. Compare to cxp to quantify this. 5. IMHO only published variables should appear in the NA variable list. Too cluttered. 6. Support TIME data type in NA 7. Access the comments field of ENUMs in NA 8. The names entered in the Safety environment/safetyIO/node-xxx/Parameters should ripple through to the IO map automatically. Not sure what I'm entering tbh. Pp

Yes they can. See the User's manual from this link Pp

No, not if you use quick response inputs or interrupt inputs.
