■Layer 2 message n parameter D
This is only enabled if Layer 2 message n parameter C is set to 0002H or 0003H.
Specify the interval for message transmission in units of 10ms. Setting this parameter to 0000H sets the interval to 0001H
(10ms) automatically.
• When the Layer 2 message n parameter C is set to 0002H, a message is transmitted every time regardless of whether data
is changed or not.
• When the Layer 2 message n parameter C is set to 0003H, a message is transmitted only if data is changed from the
previous transmission.
• A parameter error occurs if the cycle time is too short against the baud rate, whereby operation is unable to be performed
with the set cycle time.
