Hi I got a similar problem here: my ethercat chain is composed of 3 EL5032 (Endat 2.2 interface) and 1 EL3208 (8 channel input RTD). I can correctly configure the EL5032 but not the EL3208: it stays always in Pre-op conditions. However, I can correctly read the temperature via terminal and via plc using the ECATSDO command. My workaround: since I need the temperature information on a very slow time scale, I fire a PLC that perform the temperature reading via ecatsdo every 10 seconds. The major drawback of this solution is that the running time of this PLC is very high: I get a background load of +10% when this PLC is running. However, I can survive with that. Hope this helps best gigi I found that with the EL3208 you have to map all PDOs to a foreground or background task; for some reason the module only enters the OP state if you have none or all of the PDOs mapped. I used the "Load PDOs to PMAC" button on each of the 8 channels. Hope this helps :)

I have resolved this issue by assigning ALL PDOs for all channels to a background task. It appears that you cannot map individual PDOs with this particular module, instead you have to map all of the PDOs.

Hello, We have a 465 PMAC with the EtherCAT option, that we have connected to a Beckhoff EK1100 which has a EL3208 and EL1859 modules connected to it. The topology of the network is a follows: Master - PMAC 465 Slave 0 - EK1100 Coupler (has reference distributed clock box checked in settings) Slave 1 - EL3208 RTD (has reference distributed clock box unchecked in settings) Slave 2 - EL1859 DIO (has reference distributed clock box unchecked in settings) With no PDOs assigned, the EL1859 and EL3208 transition to the OP state when selecting to run all foreground tasks. We can assign PDOs for the EL1859 and run in a foreground task with no problems. However, when we assign PDOs for the EL3208 and run in a foreground task, the EL3208 always enters the PREOP + E state. I noticed that the clocks for the EL1859 and EL3208 are different, would you think this will make a difference here? I have included the output of running the 'ethercat slaves -v' command on the PMAC, below. Additionally, I can run a command 'ethercat -m0 -p1 -t int32 upload 0x6000 0x11' to read the value of an RTD I have connected to the first channel. It seems the issue is PDO related? Any help would be great, thank you for your time :) root@192.168.0.200:/opt/ppmac# ethercat slaves -v === Master 0, Slave 0 === Device: Main State: OP Flag: + Identity: Vendor Id: 0x00000002 Product code: 0x044c2c52 Revision number: 0x00110000 Serial number: 0x00000000 DL information: FMMU bit operation: no Distributed clocks: yes, 64 bit DC system time transmission delay: 0 ns Port Type Link Loop Signal NextSlave RxTime [ns] Diff [ns] NextDc [ns] 0 MII up open yes - 3356697146 0 0 1 EBUS up open yes 1 3356697746 600 145 2 MII down closed no - - - - 3 N/A down closed no - - - - General: Group: SystemBk Image name: Order number: EK1100 Device name: EK1100 EtherCAT-Koppler (2A E-Bus) Flags: Enable SafeOp: no Enable notLRW: no Current consumption: -2000 mA === Master 0, Slave 1 === Device: Main State: PREOP Flag: E Identity: Vendor Id: 0x00000002 Product code: 0x0c883052 Revision number: 0x00120000 Serial number: 0x00000000 DL information: FMMU bit operation: no Distributed clocks: yes, delay measurement only DC system time transmission delay: 145 ns Port Type Link Loop Signal NextSlave RxTime [ns] Diff [ns] NextDc [ns] 0 EBUS up open yes 0 3359145156 0 145 1 EBUS up open yes 2 3359145466 310 155 2 N/A down closed no - - - - 3 N/C down closed no - - - - Mailboxes: Bootstrap RX: 0x1000/244, TX: 0x10f4/244 Standard RX: 0x1000/128, TX: 0x1080/128 Supported protocols: CoE, FoE General: Group: AnaIn Image name: Order number: EL3208 Device name: EL3208 8K.
