SMART TECH posted a topic in Other PLCshi, i'm a beginner in automation,and i want to build a project with AC 500 HA for a redundancy application. for this reason i want an example to help to find material that i need. thank's
1756-RM2 Event Log error
JacoRoselt posted a topic in Allen Bradley / Rockwell AutomationGood day, I retreived the event log from 2x RM's today, I found on the one RM that there has been more than 700 million events. Apart from switchover events, there following event shows up a lot: (C2) Bridge Connection Deleted Starts/Stops Byte 1 (0xFF) : Byte 2 (0xFF) : Byte 3 (0xF2) : Byte 4 (0x13) : Byte 5 (0x0) : Byte 6 (0x0) : Our system: 1756-RM2 1756-L75 1756-CN2R 1756-EN2TR 1756-EN2TR 1756-EN2TR 1756-EN2TR The CN2R's are connected to 12x 1771-ACN15 and 2x 1756-CN2R in remote racks, which is also set up to be the keepers. The EN2TR's are connected to their respective ETAPs/EN2TR's in ring topology. We have experienced some issues when switching over. Hope someone can tell me what that message means regarding the Bridge Connection.
CPU 315-2PN/DP for Software Redundancy
cyrus posted a topic in SiemensHi Dears, I have 2 No. CPU 315-2PN/DP (6ES7 315-2EH14-0AB0) I want to use this CPUs for S7 300 Software Redundancy. I Have 2 CP342-5 too for IMs. I want to use profibus port of this CPU for synchronization. if this CPUs are suitable for software redundancy? or I can not use this CPU and I must to use CPU-315-2DP instead? Thanks
Omron CS1D IO redundancy
cyrus posted a topic in CX-ProgrammerHi dears, I have 2 analog input module (AD081). I want to know how can i do redundacy for analog input signals in cx programmar? I use duplicator for 4_20 mA signal. How is it for digital signals for redundancy too? Thanks.
Cpu dulpex notwork
cyrus posted a topic in CX-ProgrammerHi dears, I have cs1d plc with 2 no. Cpu65h and one dpl02d. When i download my program to cpu cx- programmar alarm that program download to simplex mode. And one cpu not work. How can i set cpu redundancy? Thanks
cyrus posted a topic in CX-DesignerHi Dears, I Have CS1D-65H Duplex control system with two CS1D-ETN21D. I want to use ETN21 for connection between CS1D and NS15 touch panel. I have question about HMI redundancy. (when one CPU is faulty second CPU connect to HMI) Note: I have one NS15 Touch panel. how can do i it? which setting is necessary in CX-Designer? and second question: i have one CP1H with CIF41(FINS) that must be connected to this NS15. means CS1D with 2 CPU and CP1H is connected to one HMI. is it possible to connect CP1H and CS1D simultaneously to one Touch panel? can i have manual for do this settings? is it possible use of FINS and ethernet (ETN21) simultaneously? best regards.
Redundancy Processor Online Modifications
GuyMiller posted a topic in Allen Bradley / Rockwell AutomationWe recently added a new analog card to a remote rack that is communicates to a processor rack that has a redundant partner... We made the change when the processor was online, do we need to do anything on the redundant side?
Disqualified Redundancy Partner IO Issue?
GuyMiller posted a topic in Allen Bradley / Rockwell AutomationI am investigating a failure that occurred... We have a L62 Processor with RIO and Redundancy, it was reported that a system "failed to stop" this system is started and stopped via outputs channels on an OW16I card on one of the RIO racks. Has anyone had experience an issue with IO not responding as it should if the redundant partner is disqualified? Also, there was a know network issue and the main Ethernet card (Slot 1) did have a communication issue (not the same Ethernet card for the RIO (Slot 3).
Lack of Primary PLC Control in CRU320 Dual Redundant system - potential Citect issue
Genew posted a topic in GEHi, I have been helping a client overseas to upgrade and install some CPE330 PLCs configured as CRU320s to replace their faulty CRU320s. They had been previous controlling primarily from the Secondary (PLC B) for the last 6 years or so until PLC B finally failed due to a power surge. Having configured and downloading the previously working project to the PLCs in their respective hardware configuration, the system refuses to allow PLC A to control via the Citect SCADA, despite showing as Active and Ready on both Citect and the RMX Modules, although no outputs are read through Citect when PLC B is switched off at all. I found this forum from searching a previous post about drivers and if 90-30 and Rx3i required any changes (their previous setup before being Rx3i was 90-30), but as you confirmed in that thread, that the driver should be fine, unless you know of any issues with it working alongside newer PLCs configured as older ones? I should note we have discovered that the firmware revisions on each PLC is different and will be getting them to upgrade the later one to coincide. Each PLC has been tested in either HWC and both operate when configured as PLC B and neither operate fully as PLC A. We've had a GE technician check over the project and extracted text files from the PLCs and has confirmed the code and config looks correct. We're running out of ideas and out next step is to try and borrow 2 PLC racks and try to run them all first hand to see if PLC A runs on the SCADA in our office to try and rule out the software altogether! Any help you can provide would be much appreciated, Gene
Modbus TCP/IP communication with controllogix redundancy
Rasu posted a topic in Allen Bradley / Rockwell AutomationI'm using Controllogix L61 redundancy system as a slave with DCS using ethernet tcp/ip socket programming. The communication between master and slave will fail after a switchover. Kindly give solution for this. Thanks and regards, Rasu
1756-RM Series B "PRI" LED Indication
GasolineBoy posted a topic in Allen Bradley / Rockwell AutomationHi, I have encountered an unexpected "PRI" LED indication of 1756-RM Series B module. When the affected redundancy module is set to primary, the status of the "PRI" LED indicator is blinking red. On the other hand, it is set to a solid red when the RM is set as secondary. I have read the manual and there are only two expected behavior for the "PRI" LED indicator, green if it is set as the primary and off if it is secondary. Does someone encountered this scenario already? P.S. The RM does not have any minor/major faults when accessed. The status indicator indicates "PRIM" when the affected module is set as primary and "SYNC" when set as secondary. Manual switchover between controllers are done and was successful. Thanks in advance! Regards, RIValencia
Redundancy causes low speed
João Augusto posted a topic in Allen Bradley / Rockwell AutomationHi, I'm using a 1756-l61 in a redundant chasis. The redundancy is working properly, but when I try to be online using rslogix the connection speed is too low. i did some tests, trying to removing one controller and breaking the redundancy and the speed came back to normal speed connection. some one had this problem? if yes, could help me? thanks joao
ControlLogix Redundancy Ethernet/IP IO Configuration
andreik posted a topic in Allen Bradley / Rockwell AutomationHi, Good day to all, I got a situation regarding the redundancy configuration. Please refer to the image attached (Page 26, Enhanced Redundancy User Manual). Notice the 1756 ControlLogix I/O inside the green box! The chassis hasn't got a CPU but only has an Ethernet IP module for the entire chassis. Does anyone know how to add and configure this chassis to the I/O configuration tree of RSLogix5K (Logix Designer 5k)? On my configuration, I've also inserted 2 MVI56E-MNETC Modbus TCP/IP Module in addition to the standard I/O Modules. Is my configuration possible? I appreciate any help I could get, thank you very much! Sincerely, Andrei O. Karunungan
