4.
Set the terminator selector to the terminator setting for the last Unit for
each Master. Check to confirm that no intermediate Units have been
accidentally set as terminators.
5.
Apply power to all Units except Masters in any convenient order. Apply
power to the Masters last. A terminator check will be automatically exe-
cuted when power is supplied to each Master. (All Slaves and Remote
Terminals turned on after their Master will be ignored in the terminator
check and will not be involved in System communications. Refer to 3-4
Delayed Activation of Slaves for an example program that activates Sys-
tem operation when a Slave is turned on.)
6.
After the terminator check indicator(s) on the Master(s) goes out, enter
the I/O table (see note 3) through the Programming Console and then
verify the I/O table. If a terminator is not found, CPU WAIT'G will be dis-
played on the Programming Console. Once the I/O table has been en-
tered, it is not necessary to reenter it each time power is turned on, un-
less there is a change in it.
7.
After entering the I/O table, specify the word multipliers if you are using
a C1000H and C2000H System. Word multipliers are not necessary in
other Systems.
8.
Begin operation in RUN or MONITOR mode.
Note
1. Once the I/O table has been generated, it is retained in the memory even
while power is turned off. If I/O table creation is not possible following
changes to C1000H and C2000H Systems, refer to 7-6 I/O Table Creation
Problems .
2. If the System does not operate properly after following the above proce-
dure, refer to Section 5 Error Processing.
3. Although C200H PCs will operate properly even if an I/O table is not cre-
ated, creating one is highly recommended with a Remote I/O System to
enable error messages. If an I/O table is not created, all Slaves turned on
after their Master will be ignored in operations.
4. If the Remote I/O System configuration is changed, regenerate the table.
5. Once an I/O table has been created, operations will continue with only the
Slaves to which power is being supplied, and any Slave that was originally
turned off will be added to operations whenever it is turned on.
The following flowchart illustrates the above procedure.
Turn on power to all Slaves.
Turn on power to each Master (i.e., the PC).
Terminator check performed (automatic).
Create I/O table.
Verify I/O table.
Start operation in RUN or MONITOR mode.
