Hello. I need to create project to manage FLOAT VALVE. Let's say that RUNNING_Time of valve is 100 seconds. Usually I would control the float valve in this way: When I start or stop the regulation, the valve would be closing for 110% of RUNNING_Time (positioning). When the positioning is done, I would start NORMAL_Operation. In normal operation I would like to drive the valve based on time intervals. If the valve is closed and the POSITION_Setpoint is 50%, I would set the DIGITAL_OUT_Open for 50 seconds. If the POSITION_Setpoint then goes to 60%, I would set the DIGITAL_OUT_Open for 10 more seconds. Does someone have this kind of sample written in CX-Programmer? Thanks. I have INPUT data for valve: - POSITION_Setpoint (0-100%) - RUNNING_Time  (120 sec) I would like to have OUTPUTS: - POSSITION_Current - DIGITAL_OUT_Open - DIGITAL_OUT_Close

I mean  NODE NUMBER set by rotary switches. I know that the last octet of IP  should be NODE NUMBER. But in my case isn't so.  So the question remains: Is this NODE NUMBER settings saved somewhere in CIO or DM area?

Hello. I'm having CJ1M unit with ETN21 card on remote site. I can't drive to the site and look at the rotary switches to determine what is the units NODE NUMBER. I can connect to the PLC remotely using CX-Programmer. Is it possible to read the setting of NODE NUMBER remotely? Is this NODE NUMBER settings saved somewhere in CIO or DM area? Thanks. BR, Andrej.

I'm already using OMRON driver. But I'm upgrading system from 6.1 to 2020. The problem is that OMRON driver support AR registers to only AR27.15 I need to read AR402.04 (LOW Battery) I know I could link AR to HR register but I have a lot of PLCs and not all can be REMOTELY accesed. In Citect 6.1 there was an easy "hack" to this limitation. You edited OMRON.dbf file. In Citect 2020 this no longer works.

Thanks for answer. I did use Host link. The driver is named OMRON. The problem is that OMRON driver allow to read A registers from A0 to A27. I need to read the BATTERY status located on A402.04. I know I can modify / copy A to HR, but I have quite a lot of PLCs to modify. BTW: FINS3 support serial communication. You must enter 0/0/0/S for PLC address. But the problem is in FINS HOSTLINK HEADER NODE (Node = 0) by default and I can't find parameter to change this number. BR.    

Hello. I'm having problems communicating with omron CJ1m through SERIAL port. I'm using OMFINS3 protocol. Settings: Citect.ini  Source: 0/10/0  10..Last IP Address (used for TCP/IP) BOARD: BOARD1, COMx PORT: PORT1, PORT Nr=1, BOARD1, 9600, 7 ,2, EVEN DEVICE: OMR_SER, Dev Nr= 1, Address: 0/0/0/S, PROT: OMFINS3, PORT: PORT1 If the Unit number = 0, this works. If I set the OMRON Unit number = 1, this stops to work.  I figured out (using Multiway) that the problem is in FINS HOSTLINK HEADER NODE (Node = 0)  [10:22:07,273]  <--:@00FA080000300000000010007010182000100000372*<CR> [!]: No response If I change the FINS HOSTLINK HEADER NODE (Node = 1)  it WORKS. [10:31:32,336]  <--:@01FA08000030000000001000801018200010000037C*<CR> [10:31:32,445]  -->:@01FA00C0000200010000000008010100008830000000003D*<CR> The problem is, that I don't know where can I change the FINS HOSTLINK HEADER NODE in Citect's OMFINS3 driver. The Citect's OMFINS3 driver always use FINS HOSTLINK HEADER NODE (Node = 0) Can you help me? Thanks.

Hello. I'm using OMRON NB Display Did someone already made time adjustment from NB to OMRON PLC? What I'm trying to do is to adjust time  from HMI to PLC. Since now I have done time sync from PLC to HMI using timer and data transfer. Now I would like to adjust current time in PLC using NB HMI. I know how to do it, but I'm some kind a lazy person. In our country there is a saying: " Don't reinvent things that already exists" Thanks.   BR, Andrej.

Not good. This is just IP Scaner. As I wrote: The IP of PLC is UNKNOWN. Not in the same subnet...  

Hello. I have CP1L EM30 with unknown IP. I have tried to use "Direct Ethernet Connection" with "Network Browser" but with no success. I have manually set the ethernet IP4 address to 192.168.20.20 / 255.255.255.0 I've got error: "The OMRON Ethernet Direct Connection Manager service is starting in Safe Mode because Windows APIPA is enabled. (0x82020003)Omron.Cxmw.Modules.SystemLibrary.SysLibException" The PLC does NOT have default ip 192.168.250.1. What Can I do? Please help. Thanks. BR, Andrej.  

Hello. Is it possible to hard reset (power cycle) the CP1L-E cpu unit using software? I'm having difficulties, because when you configure IO MAD42 card via CIO registers, you have to power cycle the PLC. The problem is, that I remotely configure the PLC. If I put PLC to program then to run mode, the configuration fails to update. Is there some kind of BIT to do "virtual" power cycle? Thanks.

I guess it has something to do with Regional Format (SL). I have to use comma (1000,0) instead of dot (1000.0).... In other software which uses structure text, I didn't have this kind of problem... BR.  

Hello. I'm having difficulties of how to write REAL constant in ST. For example (Gap1 is defined as REAL): Gap1:= UDINT_TO_REAL(P_Cycle_Time_Value) / +1000.0;     RETURNS ERROR ERROR:   Conversion cannot convert from Integer Literal to REAL I have also tried 1000.0 If I use:  Gap1:= UDINT_TO_REAL(P_Cycle_Time_Value) / INT_TO_REAL(1000);  COMPILES OK My question.. How do I write REAL constant in Structure text? I don't want to use  INT_TO_REAL anytime I want to do calculations with constants.. Thanks. BR.

Thanks for replay.  But I don't want to mess with Cycle Time. The question is: Can I get current time/date (UDINT) in miliseconds? (Similar as arduino millis())? Thanks. BR.

Hello. I'm trying to develop Tau filter wich uses time calculations like this: TimeNew := GetTime() // system time in miliseconds ExpTime := TimeNew - TimeOld TimeOld := TimeNew I guess I colud use CycleTime, but the resoult for CycleTime is not constant...
