MODBUS Interface
Verbatim Owner's Manual F-19
4 9 08 net * N
Function Reads/sets link-level timer. Units are milliseconds. Usage of
this timer is protocol dependent and described in the
appendices. In general, this parameter is the maximum time
the Verbatim will wait for the response from a
communications co-processor or interface module.
Response <net ID> link limit time is <N> mseconds
4 9 09 net * N
Function Reads/sets application-level timer. Units are milliseconds.
This value is the maximum amount of time the Verbatim will
wait for another node to respond to any command.
Response <net ID> message limit time is <N> mseconds
F.14 Miscellaneous
4 9 *
Function Repeats the previous command which began with a ‘4’. It is
possible to add key strokes after the * and before enter, subject
to limit of 65 total keystrokes. The added key strokes are not
concatenated for subsequent 49* commands.
Response appropriate to actual command resulting
In the following, N may be omitted, in which case the current value is only
announced, not altered. The values apply to all commands expecting a net or
node value to be specified. They allow fewer keystrokes to be used when
programming net addresses and other commands.
4 9 10 N
Function Read/set default net number to N. N must be 0-5, consistent
with the hardware options.
Response Default net address network is N
4 9 11 N
Function Read/set default node number to N. Allowable values for N
are protocol dependent.
Response Default net address node is <N>
F.15 Clear-Out Operations
4 9 3 * net
Function Globally disables/enables RC polling on the specified
network. Acts as a toggle, so two consecutive entries cancel
each other out. No RC programming is erased.
Response <net ID> communication is (off, on)
4 9 35 4
Function Clears all RC user recorded messages.
