CHAPTER 4: OPERATION

4.1

Configuration

Once the HE-XRZ2 is installed, the corresponding CSCAPE application must be made aware of
the optional COM module. This is accomplished through the CSCAPE: Controller -> I/O
Configuration menu as shown below:
If the target XLe (with the HE-XRZ2 installed) is available and connected to CSCAPE, the Auto
Config System will fill the EMPTY slot with HEXRZ2 information. If the target XLe is NOT
available, the user may manually configure by clicking the Config button adjacent to the EMPTY
slot and selecting HEXRZ2 – radio modem option card (this assumes that XLE has previously
been selected as the Controller). Thereafter, on exiting the I/O Configuration dialog by clicking
the OK button, the application is configured for the HE-XRZ2.
Failure to set HEXRZ2 in the I/O Configuration when attempting to download an application that
uses an OPEN function block set to Radio generates a download error. Even if the HE-XRZ2 is
not used by the application, the HEXRZ2 must still be set in the I/O Configuration to prevent an
I/O Configuration error on the XLe.
4.2

Ladder communications

To access the HE-XRZ2 optional COM module from ladder, the application must first execute an
OPEN function block for MJ1/Option port with Mode set to Radio. This function block
accomplishes three tasks:
Serial port is disconnected from the CSCAPE command interpreter and made
•
available to ladder communications function blocks.
Serial port is internally connected to the HE-XRZ2.
•
Serial port transfer rate and frame protocol set to match HE-XRZ2
