Configuration Steps
1. To select a data type, press F1 (tgl). In sequence, line 2 will display: %I (discrete
input bits), %Q, (discrete output bits), %AI (analog input words), %AQ (analog
output words). Pressing F1 (tgl) a fourth time displays the Drop ID configuration
screen.
2. With the desired data type displayed, press F2 (ref) to select the beginning Series
90–70 reference for that data type.
3. Press F3 (entr) to enter the desired data length. For %I and %Q, this is a value in
discrete bits ( P T S). It must begin on a byte boundary (a number which is 1 more
than a multiple of 8, such as 9, 17, or 25). For %AI and %AQ, the length value is in
channels ( C H S ), each of which is a 2–byte word.
The lengths entered must not add up to more than 128 bytes of inputs and 128
bytes of outputs. The Hand–held Monitor will check these totals before sending
the configuration to the Remote I/O Scanner.
4. Press the F1 (Tgl) key a fourth time to configure a Remote Drop ID as instructed
on the next page.
5. After setting up the desired remote I/O map and Remote Drop ID, press the F3
(send) key to download these selections to the Remote I/O Scanner. This causes
the Remote I/O Scanner to automatically configure the I/O modules physically
present in the remote drop at that time, as shown in chapter 4.
Caution
Pressing the F3 (send) key from this screen causes the Remote I/O
Scanner to automatically configure the remote drop. If a
configuration was previous entered from any source, this new
configuration will REPLACE it if the original configuration is not
protected. This can result in changed data lengths and Remote Drop
ID. In addition, any module options (such as output defaults, voltage
range, and input filter time) previously selected using Logicmaster
90–70 will be replaced with their default settings.
