[FONT="]Want to set up some point i/o and I haven’t used it before. When searching this forum there is a lot of info but so far not exactly what is needed. Hopefully, I can get some of the basics answered here. [/FONT]
[FONT="]1. [/FONT][FONT="]My remote location is 200’ from the 1769-L30ER PLC, before any up/down wire routes. If it happens that the cable exceeds 300’, will a powered unmanaged switch placed halfway along the route amplify the signal adequately?[/FONT]
[FONT="]2. [/FONT][FONT="]If the PLC is connected to an internet accessible router (if, if, if), is it needed to use a managed switch? If so, what does that do that is so wonderful?[/FONT]
[FONT="]3. [/FONT][FONT="]I figured out how to configure the 1734-AENT/A (Ethernet point communicator) to Logix 5000 in the Controller Organizer (tree view), and how to add point I/O modules. Is there a requirement for 1 IP address for each Point I/O Chassis? The L30ER is limited to 16 ethernet nodes. Is this why there is more than one node? [/FONT]
[FONT="]The remote part of the tree is as follows:[/FONT]
[FONT="]-Ethernet[/FONT]
[FONT="] ---1769-L30ER Generic1[/FONT]
[FONT="]- 1734-AENT/A RCOM01[/FONT]
[FONT="] - PointIO 10 Slot Chassis[/FONT]
[FONT="] [0] 1734-AENT/A RCOM01[/FONT]
[FONT="] [1] 1734-IE2C/C RI01[/FONT]
[FONT="] [2] 1734-OB4/C RO02[/FONT]
[FONT="] [/FONT]
[FONT="]4. [/FONT][FONT="]My CMore OIT will be communicating over Ethernet too. Is it a node?[/FONT]
[FONT="]5. [/FONT][FONT="]If a virtual 10 Slot Chassis for 1734-AENT is created, but then only 2 slots are used, what is wasted? Is it just controller memory? If so, there seems to be plenty of that.[/FONT]
[FONT="]6. [/FONT][FONT="]How do I address the remote data from Logix 5000? When I alias local I/O, I use [LOCAL:1:O.DATA.0] for example for the 1st bit of an output card in local slot 1. For the remote I/O, I have named the 1734-AENT = “RCOM01”. I have the following memory locations.[/FONT]
[FONT="]+RCOM01:I[/FONT]
[FONT="]+RCOM01:O[/FONT]
[FONT="]+RCOM01:1:C[/FONT]
[FONT="]+RCOM01:1:I[/FONT]
[FONT="]+RCOM01: 2:C[/FONT]
[FONT="]+RCOM01:2:O[/FONT]
[FONT="] [/FONT]
[FONT="]To alias (and later address) an input bit from the IE2C in slot 1, I expand +RCOM01:1:I, followed by expanding +RCOM01:1:I.Ch0Data[/FONT]
[FONT="]It looks like this:[/FONT]
[FONT="]-RCOM01:1:I[/FONT]
[FONT="] +RCOM01:1:I.Fault[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 0[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 1[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 2[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 3[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 4[/FONT]

[FONT="] -RCOM: 1:I.Ch0Data 8[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 9[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 10[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 11[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 12[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 13[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 14[/FONT]
[FONT="] -RCOM: 1:I.Ch0Data 15[/FONT]
[FONT="] [/FONT]
[FONT="]Is this where the data will be? Why are there 16 bits? The card can only handle 2 points – my understanding is that’s 2 bits worth (pun intended). Do i only use Data 0 and Data 1?[/FONT]
[FONT="] [/FONT]
[FONT="]Similarly but worse, with the OB4, I only see 8 bits. The output card only handles 4 points.[/FONT]
[FONT="] [/FONT]
[FONT="]Manuals: RTFM. I have this publication. [/FONT][FONT="]1734-UM011D-EN-P POINT I/O EtherNet/IP Adapter Module User Manual. It talks about all the different cards, but from my basics, i haven’t been able to get many answers from the manual.[/FONT]
[FONT="] [/FONT]
[FONT="]This is too much for now. I will stop and hopefully get some answers.[/FONT]
