　　Special note for installing the SM128V card in a GE 90/70 system rack

　　The GE90/70 system rack has no openings for the guide pins of the SM128V card. If this fact has not been considered when ordering the card, the guide pins have to be removed before installing the card. Cascade Mode Removing the card

　　In order to remove the card from the VME rack please follow these steps:

　　1. Switch off the power supply of the VME rack.

　　2. Release the screws in the front panel.

　　3. Press the two slide elements (grips) apart from each other. This will release the

　　card from the backplane connectors.

　　4. Pull the card out of the slot.

　　Fiber-Optic Connectors TX and RX (5) (6)

　　Channel 1 communicates bi-directionally with compatible devices over the TX and RX interface ports. Both ports use standard ST type connectors. TX realizes the fiber-optic transmitter while RX realizes the fiber-optic receiver.

　　Fiber-Optic Connector TX (10)

　　Channel 2 communicates unidirectionally with compatible devices via the TX interface port. This port uses a standard ST type connector. TX realizes the fiber-optic transmit ter for Channel 2.

　　Up to eight SM128V cards (Channel 1 only) may be cascaded in a single daisy-chain of fiber-optic devices. Similar to the data package concept of ibaPADU-8, the total of 64 a/d signals to be transmitted over one fiber-optic link is subdivided into eight containers of eight a/d sig nals each. In this mode, each SM128V participating in the chain can be partitioned into units with integer multiples of 8 channels. The settings of the switches S2 and S3 (Channel 1) determine the start position (group of eight signals) of the local data in the telegram on the ibaNet bus (address 1…8) and the number of signals, in groups of eight (range 1…8), that will be occupied. The setting of S1 switch is 0 (zero) in cascade mode.https://www.axcontroler.com/Product/

　　Engineering Note

　　If ibaPDA version is 5.20 or higher each connected fiber-optic link must be assigned to 　　two modules of module type “SM128”. This module type offers the possibility to scale 　　the incoming signals with gain and offset even in real format. This allows the process 　　ing of standardized values (-1.0 …0 .. 1.0) coming from the VME control system. 　　With older versions of ibaPDA assign the module type “ibaLink-SM-64-io” to the ap 　　propiate modules. Scaling of the signals is not possible. The values are expected by 　　ibaPDA in physical units.

　　ibaLogic Application

　　A typical combination of SM128V and ibaLogic requires connections of the fiber-optic output links to ibaFOB-io- or ibaFOB-4i (-S) input links. Each link transmits 64 analog and 64 digital signals, i.e. a total of 128 signals. In order to use the outputs of the ibaLogic application the fiber-optic input link at chan nel 1 of the SM128V-card must be connected to the output link of a ibaFOB-io- or ibaFOB-4o card in the ibaLogic-PC. This link receives 64 analog and 64 digital signals.

　　Process I/O Mode

　　The SM128V can serve as a process i/o bus extender for PLC systems using ibaPADU-8 or ibaNet750-BM series process input and output devices. Up to 8 iba PADU-8-O output devices can be connected to each fiber-optic output of Channel 1 and 2 for a total of 16 x 8 analog (+/-10 V or +/-20 mA, or other) and 16 x 8 binary out puts. Only daisy-chain structures are supported. ibaPDA and ibaLogic can also be connected.

　　Figure 15 System topology for process i/o application with ibaPADU-8 and ibaPADU-8-OA mix of i/o mode and cascade mode is also possible. E.g. channel 1 could be used in cascade mode and channel 2 as output. Any ibaLink-SM-64-io telegram compatible series device can be used in combination with the SM128V.

　　The VMEbus interface

　　The SM128V supports a maximum of 64 input channels (a + d) and 128 output chan nels. The card occupies 256 kByte memory space on the VMEbus. The base VME ad dress is adjustable using the DIP switch settings as described above. From the VMEbus viewpoint, WORDs and DWORDs can be read and written in BIG ENDIAN or LITTLE ENDIAN format. The SM128V-card can accept both formats. The used format has to be configured with a DIP switch. Whether the link sends in integer or float format must be defined prior to installing the SM128V. Use the DIP switch to change this setting for each fiber optic link. Each fiber optic link must be set independently. Data must then be written to the appropriate regis ters. The digital channel values may be written in channel-wise in either a DWORD for each digital channel (bit 0 of each DWORD) or an 8 byte bit mask. Prior to sending the tele gram the respective registers are OR’d to determine whether a 0 or 1 is sent in the tel egram. For this reason, it is important to reset the registers of the unused method. It’s an asynchronous take-over of data from the VME range into the buffer of the FOB transmitter. Data coming out of the VME range will be synchronized with the 1 ms clock of the FOB interface. Thus the take-over time for the data varies between 0 and 1 ms.
