(5) Refresh time with the remote I/O module, I/O module and intelligent
function module
Refresh time with the remote I/O module, I/O module and intelligent function
module is according to the formula shown below.
0.0016 + X /16 0.0024 + Y
Z
The number of I/O modules ranges as follows:
The input module is the X range set by the common parameters of the network
parameters
The output module is the range of modules mounted to the remote I/O station
(from the first output module mounted to the main base unit to the last output
module mounted to the extension base unit.)
In the formula, the main base unit and extension base units from the range
referenced above are assigned.
N + N [ms]

1: In the case of the following access (reading and writing devices, monitoring,
etc.) or relay processing, 20 ms is generated as delay time.
Without any access or relay processing, the delay time is 0 ms.
• When accessing a remote I/O station from GX Developer or GOT, or when
accessing other station from GX Developer or GOT via a remote I/O
station.
• When accessing a remote I/O station from an intelligent function module,
or when accessing other station from an intelligent function module via a
remote I/O station.
• When accessing a remote I/O station from a CPU module.
