    Hi beljic I've tried it with an NT2S-CN223-V2 to the peripheral port, and a XW2Z-200T to the host link port. No luck. Will the NT3S-126 work? And... Thanks for your help

    Hi This must be something straightforward, but I can't get an NT3S and a CJ to talk. Anyone confirm the hardware required, and which protocol to go for? Cheers Pp

    Hi Are you seeing AC9 alarm? The serial comms motor to amp is not user editable. It either works, or doesn't. Has it just started, or has it never worked? I'd check wiring, and the fact that it's a Sigma2 motor, too. Out of interest, the cable you need to connect to the amp is JZSP-CMS02 Pp

    Hi I have three CPM2C that I'd like to share data between. It's actually the Inverter PLC type, but I don't think this is important. Is there a manual that details how to achieve this, i.e. from what hardware is required, to what commands I should issue in the ladder? There's an RS422 port, so I guess I can daisy chain between these, but would appreciate input form someone who's done it before. Thanks

    Hi, and thanks for the replies. Found the EDS (In comms adapters rather than I/O). Looks good. Here's another CX-Integrator question. If the slave gives me 10 bytes, can I map the first two bytes to one memory area, and the rest of the bytes to another area? Thanks guys

    Hi Anyone know where I can download the EDS file for SmartSlice? Developing a system, and wondering how the I/O size from each node is determined? Thanks. Pp

    File Name: Useable timer File Submitter: ParaffinPower File Submitted: 8 Mar 2006 File Category: PLC Sample Code Hate BCD? Me too. Here's a timer FB that uses wait for it an INTeger preset. Easier to scale gives you the time remaining done bit and a timing bit. Use one of the system bits (P_1s etc.) to set the timebase. Click here to download this file

    From CX-Designer, you can right-click the SAP and select edit from the context menu. Not sure how to edit scaling, though - be interested to find out. Pp

    Hi The R7D needs the encoder input from the motor. The SmartStep closes the loop between motor and the amp, but not back to the motion controller. This is why they're cheap. Are you trying to perform closed-loop control from a CJ1? Might be tricky. The CJ1M 22 will fire command pulses at the R7D, and can receive an 'In Position' input from the R7D which is better than nothing. I don't think the encoder output is available on CN1 (cheap, again!) I'd suggest using the Omron cables/breakout board to connect CJ1 to R7D as there are resistors required to drop the pulse voltage from 24 to 5vdc. If you want part numbers then let me know. Pp

    Hi. I have a project using V700 tag readers. In CX-Programmer's FB library, there are FBs to talk to V600's. Are these likely to be compatible? Thanks, Pp

    File Name: Tracking product on conveyor File Submitter: ParaffinPower File Submitted: 12 Feb 2006 File Category: PLC Sample Code Products arrive on conveyor irregularly pitched. Conveyor is equipped with an encoder or maybe a proxy looking at the sprocket. This program captures the position and then multiple FB calls can be made to give an output at a distance from the input point maybe at a label inspction point or reject unit. The Shift register readout FB can be called as many times as necessary. The encoder can be connected to a high-speed counter meaning that the PLC scan need not 'see' every number i.e the encoder counter can be asynchronous. I've simulated this in this program by incrementing the 'encoder' with a timed interrupt. Adjacent to the product position stack is a product status stack so data can be written in at any point too e.g. I'm in front of the label detect sensor - if it's on then I can enter a '1' (say) into the stack. As the status is kept in a Word then upto 16 devices can write into the stack. Subsequent writes are ORed with existing data. This can be achieved with FIFO but this method is more efficient as data is not actually moved just pointers to the data. Click here to download this file

    Hi folks Using an L7 inverter (well a few between 5.5 and 11Kw) with the PLC option board. I have an NT2S hmi connected. Here's the thing...when the inverter is stopped, comms is fine; when the inverter runs then comms is interrupted, indicated by '!!!' in the variable fields. When the inverter stops again, comms is restored. I guess it's noise related. The cable to the screen leaves the power wiring as soon as it can - i.e. straight out. One more thing. I'm using the transfer data option to read D1-01 to D1-07 (Memobus address 280-287) in one hit. I'd like to get to D1-08 to D1-17, but the memobus addresses are not sequential. Will I have to issue separate read commands, or will it compensate for the 'gaps'? Any thoughts? Thanks -Pp
