62 VisiLogic: Getting Started
This error can generally be resolved by downloading a new VisiLogic project
updating the current project to the most recent version of VisiLogic. You can
also update the project currently in the PLC by uploading it, updating it, and
then downloading it to the PLC.
Known Issue, Vision 120
Known issue: A power failure during OS download causes V120 models,
installed with bootstrap (firmware)1.30 and lower, to enter bootstrap mode.
The V120 will not be able to exit Bootstrap mode until it is physically turned
off, and then powered on.
Downloading an OS via Modem
By following the recommendations given below, you can successfully download
an OS to a Vision controller via modem. Download via modem is supported by
OS V3.70, B50 and higher.
In order to download an OS via modem:
1. Prepare and connect the PLC-side modem as described in the topic PLC-
side Modems, in the section 'How to enable a controller to communicate
via landline or GSM/GPRS modems'.
These procedures initialize the modem with the parameters required to
download an OS.
2. Connect the modem to COM port 1 on the PLC.
If power failures occur, or if the modem communication link is broken, the OS
download stops. Controllers V230, 260, and 280 can recover without any
intervention; as can V120 controllers installed with bootstrap Version 1.30 or
higher.
However, a V120 controller installed with bootstrap versions lower than 1.30
may require physical power-up (must be turned off, and then powered on.)
In all cases, it is recommended that someone be next to the PLC during the OS
download in order to attend to any potential problems.
The PC-side and PLC-side modems must use the initialization defaults: baud
rates must be set to 9600; and COM Init set to ATS0=1.
Once the PC-PLC modem connection has been established, proceed according
to the instructions in Downloading an OS.
Modem Tips
To avoid compatibility problems, use modems produced by the same
manufacturer and of the same model. This is due to lack of standardization
between modem manufacturers, which may result in communication conflicts.
Check CANbus Network Status
The network status is checked via the bridge. Access Check Network Status by
opening the Connection menu, selecting Communication & OS, then clicking
the network tab.
