The P5H-154 is a programmable device that provides Ethernet function. Because this product equips 4 digital input ports, you can transfer the signals of the ports to remote hosts via network.
Programming on this product requires the use of PHPoC (PHP on Chip). PHPoC is quite similar in syntax to PHP, the general-purpose scripting language. Therefore, anyone with experience in programming can easily learn and use it.
※ Although PHPoC and PHP are quite similar in syntax, they are clearly different programming languages. Refer to the PHPoC Language Reference and PHPoC vs PHP for detailed information.
