CHAPTER 8: COMMUNICATION OPTIONS
8.1 Overview
To supplement the built-in MJ1, MJ2 and MJ3 serial ports, additional communication options are
available. This is accomplished by installing a COM module in the XL7 OCS controller.
Previous OCS controllers shared a serial port with the communication options. The XL7 has a separate
serial port which allows using MJ1, MJ2, MJ3 and the communication options simultaneously. Internal
to the XL7 OCS, there is a CPU board, and up to two installed modules. Models HE-XW100 /
HEXT391C100 have no installed I/O or COM modules. All other models have an I/O module in Slot 1 and
could have a user-installed COM module in Slot 2. A blank I/O board kit to support a COM module in
these models is available.
This chapter briefly describes the Modem COM module options. For detailed information regarding
these modules, please refer to the individual documents provided with the modules.
8.2 Modem COM Module (XMC) Option
A Modem COM module can be installed to allow Cscape programming of an XL7 OCS over a dial-up
network. In addition, the application ladder program can take control of the modem for application-
specific modem communication.
The Modem COM module supports the standard AT command set and can connect to the dial-up
network at speeds up to 14.4 KBaud. Connection speed is auto-negotiated. The Modem COM module
connects to the dial-up network (phone line) via a cable with a standard RJ11 modular plug.
To enable Cscape programming via a dial-up network, the Modem COM module should first be
configured as the Default Programming Port, using the XL7 OCS System Menu. Doing this puts the
Modem COM module in auto-answer mode, so Cscape can call the XL7 OCS via a remote modem.
To program the ladder application to communicate via the Modem COM module, standard Cscape Serial
and Modem function blocks can be used.
