Driver Selection
The Uni-Telway Master driver is used when the target device is
configured as aUni-Telway Slave.
The Uni-Telway Slave driver is used when the target device is
configured as aUni-Telway Master. Also, this driver can communicate
with the Master devicewithout disrupting the communication from
another slave device (for example, aPC using the programming
software).
Note, though, that occasional driver timeouts will occur if the
master, or otherslaves, make the network overly busy. Driver
communication will resume whenthe network is free to accept new
commands.

* System memory is allowed to be Read/Write. However, some
addresses willnot accept a write, and some may change the operation
of the device. Theprogrammer is responsible for knowing the
function of the system data, andaccess those items
appropriately.
** A Timer/Counter Value write that is not accepted (e.g. timer
is in reset) does
not generate a communications error. The user must retry when
the properconditions exist.
Note: A Byte write operation is performed as a write to 8
separate bits.
The W command is present to convert databases made on previous
versions ofthe driver. Former W instructions are automatically
converted to MW.
