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.
