MPAQx is an optional setting and can be used to specify an analog quantity to be
formatted into a single message as described next.
Use MPTXx to construct the desired message. Note that by default the analog
quantity value, if specified, will be added at the end of the message, rounded to
the nearest integer value (see Example 6.1).
EXAMPLE 6.1 Setting MPTXx Using the Default Location of Analog
Quantity
MPTX1 := THE LOAD CURRENT IS
MPAQ1 value = 157.44
Formatted message out when triggered: THE LOAD CURRENT IS 157
Location and resolution of the analog quantity value within the message can be
specified by using “%.pf”, where,
% defines location of the value
p defines number of digits (up to 6, defaults to 6 if omitted)
f indicates floating point value (use %d if nearest whole number is desired)
EXAMPLE 6.2 Setting MPTXx With a Specified Location of Analog
Quantity
MPTX1 := THE LOAD CURRENT IS %.2f AMPERES
MPAQ1 value = 157.44
Formatted message out when triggered: THE LOAD CURRENT IS 157.44
AMPERES
MPTX1 := THE LOAD CURRENT IS %d AMPERES
MPAQ1 value = 157.44
Formatted message out when triggered: THE LOAD CURRENT IS 157

Configuration
You can configure the SEL-2414 with up to four DI cards, one in each of the four
available slots (slots C, D, E, and Z). Because of the flexibility of inserting I/O
cards in any of the assigned slots, each connection has two numbers. The first
number refers to the physical position (rear-panel terminal number); the second is
a software reference number. To determine the software reference number, the
device senses the position of the installed cards and adapts the setting names
accordingly. Use the software reference numbers to program the I/O in the
device. Table 6.15 shows the slot number and prompt correlation for a DI card.
Rear-panel terminal numbers are the same for all three types of I/O cards. State
the rear-panel terminal numbers on schematic diagrams to show wiring connec-
tions. Table 6.16 shows the rear-panel terminal number and software reference
number correlation for a DI card.
