Clear enough! I appreciate your support! Thanks again!

Thank you Ken, for clarifying the approach of the 1761 NETENI to other ethernet/ip devices. After a couple of documents read related to ETHERNET/IP, I noticed that the SLC 5/05 has other messaging capabilities such as the EEM output that can initiate CIP messages. Have you ever try touse this output function as a standard messaging among other non SLC devices? I also have read several topics in this FORUM giving as a recommendation to use other devices to do multiprotocol conversion when using other non SLC or AB devices.

Hello guys, I would like your help confirming the 1761 NETENI function. As in the AB manual 1761 UM006E says: Peer-to-Peer MessagingThis chapter describes messaging between the ENI/ENIW and DF1devices. The following topics are covered:• Messaging Between the ENI/ENIW and DF1 Devices• Message to Configuration Nodes (Nodes 100 to 149) andSending a Message to a Destination Controller (Nodes 0 to 49)Messaging Between theENI/ENIW and DF1 DevicesThe ENI/ENIW can route a DF1 message received from the attachedcontroller to a compatible destination TCP/IP device, using DF1 nodeaddresses 0 through 49. ENI/ENIW Node addresses 100 through 149store TCP/IP destination addresses. When the ENI/ENIW receives awrite message to nodes 100 to 149, it stores the TCP/IP destinationaddress in the corresponding map register.To configure the destination TCP/IP addresses, you can use either theENI/ENIW Configuration Utility, or you can send a 485CIF/PLC2message to each node as described in this section. EtherNet/IP Connectivity The 1761-NET-ENI and 1761-NET-ENIW provide EtherNet/IPconnectivity for all MicroLogix controllers, CompactLogix controllers,and other DF1 full-duplex devices. The Ethernet Network Interface,ENI or ENIW, allows you to easily connect non-Ethernet controllersonto new or existing Ethernet networks and upload/downloadprograms, communicate between controllers, and generate emailmessages via SMTP (simple mail transport protocol).EtherNet/IP is an industry standard open protocol which providesinter-device compatibility. You can exchange information with otherAllen-Bradley Ethernet controllers (SLC, PLC, and ControlLogix) in apeer-to-peer relationship, so you do not need any master-type device.The ENI and ENIW also support an SMTP mail service that allows anexisting controller to send email messages to any destinationconnected to the network. The email can be used to initiate thetransmission of data or status information. Is it possible to send a TCP message to an TCP/IP device which is not an SLC? In this specific case I have a 2D reader QXHAWK which has TCP/IP communication capability and it can be commanded remotely by using a special command language. The thing is, as long as there are no register to access in this reader as in the SLC controllers when using the MSG instruction to write or read, what should I use as the DATA TABLE ADDRESS in the TARGET DEVICE segment of the message setup? Or does it the NETENI is only focused to messaging between SLC, Micrologix and other AB devices only? I'll appreciate any comments. Regards,IA

Just a few comments to close the loop. I still don't know the reason of the instruction message with the node 0 (usually the PC RSLinx node) on the SLC. After getting plugged to the DH+ network, I could see node 6 and 7 and 5 for the SLC. After a couple of hours of reading I fall of the bed and wake up of the dream of DHRIO CLX card been PnP :) Silly me! DH+ module card on the old QUICKPANEL can see all configured register on the SLC500 memory map, and also can see everything in the ORMEC CU. I won't be able to change the communication driver on the QUICKPANEL since its the same for the ORMEC CU. According to the readings, I think I can exchange information between SLC and CLX, I just have to find how to map everything right to: let the SLC talk through the DH+ network to the QP and ORMEC CU and then get the CLX message to the SLC via the same DH+. Then, when next investment wave for upgrades come, the QP and ORMEC CU will be updated.

   Thanks Ken, according to the "Good luck!" phrase I hope this migration can turn in a nice, soft and educating experience. Thanks for your always prompt and helpful response!

Hello everyone, We're migrating an SLC500 platform (5/04) to a ControlLogix platform. The controller DH+ port is daisy chained to an OLD CU from ORMEC and and old Quickpanel HMI. Looking at the ladder logic of the SLC indicates that HMI interacts through the DH+ network with the ORMEC control unit as all the settings related to motion control are in the HMI and nothing in the PLC. There are only 4 message instructions in the ladder logic as shown in the SLC messages file attached. Reading several posts and the 1754-um514 manual I'm using the instruction message with the settings as shown in file CLX message and CLX message 1. I'm a little confused regarding the path in CLX, in SLC there are two write instructions and one read instructions all to the same node address and only read one to the local address 0. As I don't have the QuickPanel HMI program I can imagine that node 0 is the HMI as the SLC controller Chan1 node address is 5. And also I assume that node address of the ORMEC CU is 6 as is the one with more registers and the comments of the message instructions refer to it. On the path of the message instruction of CLX I'm using the chassis backplane and the slot of the DH+/DHRIO module to output the message. Is this correct to emulate what the SLC instruction were doing? Regards,

Here is the program post. to_post_STA45_DTM_Rfbshd.ACD

It is an INT data type. I'll try with the other two options.

Hello Gerry, Array is a tag of a user-defined type. a specific user defined data type was created named: udt_Part, then a Base tag was created making reference to the data type udt_Part just created. udt_part contains: PartInfo which is a userd defined data type length 100 ... This is the data array part info contains: Parameter1 which is a string 16 Parameter2 which is a string 16 Parameter3 which is a string 16 Parameter4 which is a SINT length 5 Parameter5 which is a INT length 20 Thanks for the support,

Hello b_carlton, actually yes, the syntax checker has no problem if I write a number instead of the "index element".

Hello guys, I need some help regarding indirect addressing: There is a user defined array data type integrated by the following elements: Array user defined data type Array.ArrayInfo user defined tag size 100 Parameter1 String16 Parameter2 String16 Parameter3 String16 Parameter4 INT size 5 Parameter5 INT size 20 I'm using Array.ArrayInfo[index_element].Parameter4[1].0 to check bit 0 of element 1 of array parameter4 but an error of data type rise after trying to accept edits. Is this error related to the user defined data type? Or, Am I using an erroneous format to address the data type to the bit level?

I changed SP3 to SP2. Still the same! System overhead time slice is 10%.

Ok! what I forgot to mention is that it doesn't happen the same using another computer, the one with the problem has WindowsXP SP3 up to date! Where can I check the overhead time slice? I can give you that info once I get it! Card drivers are ok as I can get access to other serial communication type devices.

Hello, my best wishes for you all on this 2009!! I´m having the following problem: After getting connected with RSLinx Classic Gateway 2.52.00.17 using DF1 protocol with a ControlLogix CPU suddenly it get's disconnected and I have to start the connection procedure all over again! I´m using an express card RS232 serial-to-usb adapter and it does the same when using a conventional USB to SERIAL converter. I've been using this converters long ago and never have problems with them before. Is there a special card I need to use from AB to gain a reliable connection with the ContolLogix CPU's family controllers? Thanks in advance!

Hi, I'm reading A970 Manuals and I still haven't found nothing regarding supported comms with DirectLogic CPUs. Does anyone knows if this PLC Brand is supported by MITSUBISHI HMIs? Thanks!
