E5C-T Digital Controllers Programmable Type Communications Manual (H186)
The host device is detecting the
absence of a response as an
error after broadcasting a
command or sending a software
reset command.
The Controller does not return responses for broadcast or
software reset commands.
2-2
2-17
4-2
4-14
The host device sent another
command before receiving a
response from the Controller.
Always read the response after sending a command
(except for broadcast or software reset commands).
---
The host device sent the next
command too soon after
receiving a response from the
Controller.
Wait for at least 2 ms after receiving a response before
sending the next command.
1-2
The communications line became
unstable when the Controller’s
power was turned ON or
interrupted, and the host device
read the unstable status as data.
Initialize the reception buffer in the host device before
sending the first command and after turning OFF the
power to the Controller.
---
The communications data was
corrupted by noise from the
environment.
Try using a slower baud rate.
Separate the communications cable from the source of
noise.
Use a shielded, twisted-pair cable for the communications
cable.
Use as short a communications cable as possible and no
not lay or loop extra cable.
Do not run the communications cable parallel to a power
line to prevent inductive noise.
If noise countermeasures are difficult to implement, use an
Optical Interface.
