void eRelayBlock (u16 eRelayID, u8 value)
|eRelayID : The module's ID (port block number) (0 through 9)|
|value : 0 through 255|
Sets the output state of all ports in the given port block, eRelayID. value is a bit array corresponding to the 8 individual ports in the port block. If eRelayID were 1, value's bit 0 would correspond to port 10 and value's bit 7 would correspond to port 17.
eRelayBlock(1,7); // Ports 10-12: ON, Ports 13-17 OFF // 7 = b0000 0111
*Keep in mind the Expansion Relay Output Module's maximum on/off switching speed is 10 times a second (10Hz).
