5.1.4 Operation with Host SCADA program
The Host SCADA program controls the operation of the 5901 modem by sending configuration
commands, or strings of commands to the modem. These commands are referred to as AT
commands. See section 10.2-AT Command Guidelines for information on how the AT commands
are structured.
The documentation for the Host SCADA program used will contain information about how to send
AT commands to the modem.
5.2 Operation with Programmable Controllers
The SCADAPack or TeleSAFE Micro16 controllers can control the operation of the 5901 modem
using TelePACE Ladder Logic or C Tools programming software.
To configure the SCADAPack or TeleSAFE Micro16 controller and the 5901 modem for successful
dial up communication the following steps are recommended.
Configure the controller serial port to use the 5901 modem.
Initialize the 5901 modem.
Initiate a dial-up modem connection with another controller or SCADA host.
Communicate with another controller or host after dial connection is made.
5.2.1 Configure Controller Serial Communication Port
The serial communication port that the controller uses to connect with the 5901 modem must be
configured for RS-232 Dial up modem. The controller serial ports are configured using the
TelePACE program. To configure the controller serial port:
Select Controller from the TelePACE menu bar.
Select Serial Ports from the Controller menu.
In the Controller Serial Ports Settings dialog select RS-232 Dial up modem in the Port Type
selection for the com port being used.
5.2.2 Initializing the 5901 Modem
The modem initialization setting determines the 5901 modem operation when the application
program in the controller initiates a dial out or when a dial in is received from a remote modem.
Application programs usually require that the modem be initialized at the start of the program.
TelePACE Ladder Logic uses the INIM function for initializing the 5901 modem. Refer to the
TelePACE Ladder Logic Reference and User manual for complete information on this function.
