Com Profibus IO Configuration

I'm attempting to use the ET200S IO for the first time. The DP master will be a 555-1105. The DP Slave is an IM151-1. I need to use 120 volt AC discretes. When I configure my IM151 with the 6ES71314EB000AB0 2DI and with the 6ES7132HB010AB0 2DO modules, the Identifier field shows them as 8DO and 8DO. When I export the binary file, and then merge it into my 505 software, the modules show up as 8 inputs and 8 outputs. They should be showing up as 2 ins and 2 outs.

Any help is appreciated!

Juice76,

I had a similar 'problem' when I configured an ET200S (IM151) to work with an S5 115U, profibus master IM308C, I used 4 DI and 4 DO modules in the IM151 and I know that a byte was allocated to each module, so I effectively lost 4 bits per card in the IM151 rack, I could only use the first four bits (I0.0 to I0.3 for example), that might be the case for you as well, but you loose 6 bits per card.

Thanks Paul. According to Siemens Tech Support that is the case. I just wanted to hear from someone else because the tech support guy I was talking to kept laying the phone down, and asking someone in the background. I didn't have a lot of confidence in what he was telling me.

I suppose it's better he (tech support) does ask someone who does know than just guess at an answer to give you.

This forum is the only tech suppport I use!

Juice76,
If you are using 505 WorkShop and are in warranty for support, you can always call FasTrak's support people for this also.

Hi Juice

I'm digging back in my memory to the last time I used TI, but don't you have the option to 'combine' I/O addresses or something like this? So you can have a virtual module in the I/O config which consists of both DI and DO?
Anyway, I don't think losing a couple of bits in a 555 should cause too much pain - again I seem to remember you have an enormous address space in that CPU?

If I remember correctly, for the TI505 PLC's the I/O foot print per module in a Profibus slave is bounded by the original 505 module I/O count steps such as 8, 16, 32. I had encountered this same thing in the past when using a ET200L-SC, and the Smart Connect hardware was much like what the ET200S came out to be.

As far as I/O available, with a 555 you have 8192 I/O points addressable through the I/O image register, and these 8K of points can be word or discrete. As if that's not enough I/O, the CTI Profibus card maps into V-memory; so you have a number greater than 8192 possible.
