15.3.5.5 CAN Gateway
The process image size of the CAN Gateway can be set in the specified sizes of
8, 12, 16, 20, 24, 32, 40 or 48 bytes.
The CAN Gateway has an acyclic communication channel (Mailbox) in the
process image.
This is used to transmit configuration, parameterization and diagnostic data.
The length of the first acyclic channel can be set between 2 and a maximum of
x bytes (x = total PA size - 3). This is followed by the CAN user data area, where
CAN telegrams are transmitted via the "Mailbox 2.0" communication mechanism
in the operating modes "Sniffer Mode" and "Transparent Mode". In the operating
mode "Mapped Mode", in this area transmitted and received CAN telegrams can
be mapped to the process image without using any protocoll.
The operating mode and also the mailbox and the process image sizes are set
with the startup tool WAGO-I/O-
CHECK
.
