Advanced Programming

Example: Customize

When configuring Alarms (Section 6.5.3), Signals (6.6.2), or Controls (0), an option to CUSTOMIZE will be

presented at the bottom of the screen, see Figure 96 below. This enables the Supervisor to program separate

triggering equations into the CXC software. The equations may reference any combination (up to 16) of the

analog inputs, digital inputs, virtual inputs, and alarms (such as Load Voltage shown below) utilizing logical and

arithmetic arguments that simulate the functionality of a programmable logic controller (PLC).

Tips on Programming

Square parenthesis [ ] are reserved for CXC signal names.

Use only round parenthesis ( ) for manipulating the order of operations in an equation.

The counters will increment approximately every half-second by default. A cascading counter can be written to

create a longer time between increments.

Here is a delay counter for AC fail alarm. The “AC Fail Delay” works by counting up from 0 to 30 when Rect. AC

Mains Fail alarm is true. When Rect. AC Mains Fail is false it will count down to 0.

[AC Fail Delay] + ( ( [AC Fail Delay] < 30) * [Rect. AC Mains Fail] ) - ( ( [AC Fail Delay] > 0 ) *

![Rect. AC Mains Fail] )

Here is a custom signal set up to filter the battery voltage. "Filtered Battery Voltage" is the custom signal name:

( ( [Filtered Battery Voltage] * 15 ) + [Battery Voltage] ) / 16

This chapter provides definitions regarding Ethernet, IP Addresses, and CXC communications (port)

configurations.

Ethernet Port Configuration

About IP Addresses

IP stands for Internet Protocol. Every device on an IP-based LAN or WAN network (including the CXC controller,

as well as PCs, and routers) requires an IP address to uniquely identify the source node or destination node for

packets sent across the network. This applies to WAN and LAN connections. There are two ways of assigning an

IP address to a network device: Static IP Address and Dynamic IP Address.
